Hi! I'm new on the forums, I hope this is the right place to ask, I've seen similar threads here and I desperately need help.

I've been growing more and more preoccupied with the status of our playgroup recently, these last few months the most. As for a little background, we are a group of four friends, consisting of two couples: A and B and C (my partner) and myself.
We have been playing for about 15 months, starting a second campaign about 8 months ago but we've known each other for around 8 or so years I would say.
Our campaigns are very story-driven and we play through text as to have everything written down (One of the players would like to make a transcript or similar once we are done) so they tend to take a little longer.

That's all fine, here's where the first problem comes in: We play usually three days a week at least... 10 hours. It's come to a point where it's more of another chore and I'm really starting to miss having my weekends actually 'free', thankfully I work from home and my schedule has allowed keeping it going but there was a period of time where C was completely destroyed by how much we had to play and then go back to work on Monday as normal. I think it's reasonable to say that no matter how much you like playing this is just way... too much; A and B finished their studies around October of last year and haven't been working since then, so they have A LOT of free time, which is fair but even if that was the case for C and I, personally I think playing any more would be just crazy: which they wanted to do when quarantine started over here, and they were mad that we didn't because, according to them: "Everybody else is playing more D&D now and we have to play the same *insert sad GIF*" Oh, and they also have been hinting that we should play more cause summer is around the corner... im sorry but no
This absurd schedule also caused another friend of ours, who is a 'veteran' in roleplaying and D&D, to pass up in joining down the line since they could only play on Saturdays and A and B wouldn't allow for just a session a week; when we had other instances of only being able to play one day they would say "if we are going to play that little we rather wait for next week" which has always confused me? I think playing a little bit is better than nothing...
Also, whenever I go to have dinner (as it's during the evening) the session keeps going, A and B rarely wait for me to come back and it makes it seem that my character has suddenly died.

This week my family got permission to visit a family member that's in a retirement home and the first thing they did was to complain there wasn't going to be D&D this weekend... And, I get it! It's fun but we've had like... At least 24 sessions without interruption due to Corona. It makes me feel extremely guilty because, as I said, them being unemployed means C or I are the only ones that have to cancel sessions, they rather cancel THEIR own family stuff etc. just to play D&D.

And that's the tip of the iceberg, there have also been problems within the game which I'll get onto now which you may skip if you aren't interested.

I was writing more anecdotes but I realized this is way too long,  it's just that after this incident I started to grow even more insecure of how I roleplayed (I've always seen myself as the worst of the group) and although C has always ensured me that I'm doing fine and that I should not worry my head tells me that is just because they are my couple they would say that.
And when I say everything started fine I do mean it, everyone was engaged with everyone and since B and I draw we did drawings quite often of all the party/scenes etc. I feel it was around the period of time I did not want to play that they started to ignore my character and A and B's focus started to drift away from the feeling of group and we became 'divided' (since my character hangs with an NPC that joined the party since they are the only one that truly pays attention to them)

Which ties in that I personally think B is just waaay to obsessed with the campaigns, but only really with their and A's characters and nothing else. B loves A's character to the point of making the character of the first campaign OOC a lot of the time plus used to ship them together (not in-game), which didn't work out and then when the second campaign rolled in B shipped their new character with A's old one right away... Although they have NEVER interacted as the stories take place five years apart (But C did allow for B's second character to join in a possible future, just, not now) is this because they are a couple? I don't know! But it gets a bit suspicious when B pays more attention to A's DMNPC which was briefly with the party then the rest of the group. Now, don't get my words wrong, I'm not saying it's bad to like your characters, quite the contrary and I'm happy that B has found such a creative outlet: they've made tons of drawings, physical stuff with said drawings and planned even more like mugs and bedsheets, that's really really nice! But I can't help to feel... left out? Especially since during the beginning, they added everyone but now it's just... A and B's characters and due the fact they stopped adding my character to the drawings was around the time I was feeling so bad and haven't since then... It makes me feel very bad, as if I really did do something wrong and they feel that way about me too. On a side note I just don't have that much of stamina/time to create artwork yet whenever I do I always try to include the whole party since we are that, a group. I even got a couple of commissions during Christmas for all their characters even if they had been ignoring mine for long because I really thought everything was fine.

We have talked about this but the first time, around a year ago, where I explained that playing so much was taking a toll on me and how I roleplayed, as you might have guessed it was completely ignored. In the discussion two months ago they said they would try to understand my character more but I haven't seen much change as they keep leaving her behind and have their characters bond or B's character gets in the way of my character and A's bonding.

Oh! I forgot to say but A also makes a chronology of important key points but after this, I couldn't help but notice that in a lot of cases they flat out skip on things my character has done or just say "the group did..." when it was my character that did said thing. Yet as soon as my character didn't participate as much just attribute it to A and B's characters - really makes me feel like I'm worth less (Seriously, A's character has 55 entries, B's character 35 and my own 16 :s )

Tl;dr: I'm tired of playing so much D&D while simultaneously feeling left behind by a group that mostly thinks about themselves. Making it seem everything is fine but then bottling up everything up in an explosion that could be summarised 'your character isn't letting ours shine' while also leaving passive-aggressive messages in their social media. Due to their attitude, I don't know how to approach this or if I should even do it and it's making me feel very insecure.

I just no longer know what to do and I really need some hindsight and advice, C is completely burnt out, having affected how they feel about them due how I'm being treated, and it really pains me since it should be something fun, it's got to a point where I do not know if I'm just being too negative or we should really do something...
I also apologize how long this got, there are even more details I left out which I could talk about if this feels like incomplete information :(

Burnout happens. When it does it's a great time to take a break and enjoy life outside of the game. 10hrs 3x a week is a lot! For comparison I DM 5hrs one day every other week. Lol. 

Just might be time to find another group or have a good sit down with the others and just talk about it. Tell them how you feel and just be open and honest. If they complain or seem like they don't care then I'd leave. 

You're already being ignored and they make your actions feel worthless. That alone is enough already. 

If playing a game that's supposed to be fun brings you misery then it's time to go. It may take time to find a new group but it'll happen. Always a DM out there, including myself, that is thinking of starting a group or another one. Just keep your eyes open to the looking for group section and start talking to people.

Hope it all works out. 

Well there's a lot to unpack here, but first and foremost it sounds like A & B need to find another group to play with. I DM for a regular weekly group, but three people in that group have another game going with some other folks, and I also am a player in yet another group of friends. Different people have different time budgets, and these tend to evolve and change when a group lasts as long as yours. People go to school or they finish school or they have a kid or they find a partner or they lose a partner or win the lottery and can just play D&D 24/7.

So if they could spend half their available D&D time with another group of players, maybe your game would become much more manageable for you and C and they could calm down a bit.

It's hard to say if your other issues are being amplified by that point of stress or not. They might recede a bit or they might be a sign of a deeper divide between what each of you are looking for in a game. Sometimes it's more than schedules that grow apart. Maybe you guys could find others to play with as well that were a bit less... well "immature" comes to mind but maybe that's not fair. It sounds like that's how you feel though.

Either way, if that's the way things are going, it would still likely go a lot smoother if A & B had an additional outlet to play D&D and put their energy into. That's the first step I'd try to make.

To start with, I think that its just too much D&D. Let them know that unless things get scaled back (to like 1 session a week), that you and C won't be joining them.

The attitudes are harder to deal with, seems like a break and finding a different group might be for the best.

That's a lot of D&D!

As other suggested, the best solution would be if the people with more time or willingness play another campaign aside, and you play with them the current one but maybe once per week.

Back on my days I had a group of 6, we were running two campaigns (one with all 6, other with 5 as one player wanted breaks). But 4 of us wanted more since we had a lot of free time, instead of pushing the whole group, we created another campaign. It was very cool as we could experiment with different classes and even systems.

I don't know your group and outside-the-game relations there, but this sounds like a rather unhealthy level of attachment of A and B to the game. Ignoring the needs of other members of the session and also not putting their real relationship aside for the game is also a no-no for me.

Also 3x a week for that much time is unsustainable for every person with a job and a larger circle of friends and family. My group of 5 manages one Sunday of 8h playing every second week on average.

From my perspective this needs serious talking or termination of this group.

No good will come of this.

When I was in University I was obsessed with D&D, but we didn't play as much as your group...

A&B are ****ed up in the head tbh with some serious mental issues.  You need to get away from them as fast as possible before they destroy your lives and your soul.

You have as much right to get your way on the schedule as they have to get their way.

And no one can make you play D&D. You can always say look, I can only play once a week. If A and B are really your friends, they will accept that. If not, then you learned something valuable, and you will need to find other, more reasonable, people to play D&D with.

My gosh that is a long post.  I will confess that I did not read it all...  yet I still have advice.

     You are the master of your own schedule.  If it’s too much for you, tell them.  Set limits.  Try to be nice about it but also be firm.  Worst case they get mad and drop the game and, we’ll, worst case solves the problem too.

Take a break!
Like right now. You need at least 2 weeks off, perhaps a month from all D&D. Chill. Find time to reflect on yourself and your friend's behaviours. 
Say: "I need to take a break."

Talk it out
Speak to your partner about it. Get some perspective other than yours. If you can talk to them about it and have a heart to heart, do. Include your feelings of inadequancy around your roleplaying chops. It's more than likely just in your head and they're so self-absorbed to really not see your play as negatively as you do. 
Say: "This is how I feel about..."

Boundaries!
Get some and announce them. Figure out what would make you happy in terms of scheduling and let them know in a calm friendly manner. 
Say: "I can commit to one night a week, if you're interested."

Friendship is not conditional on you being endlessly available.
If they make you feel bad for you boundaries, they are not friends. Sorry, but move on - these people aren't all that nice. 
Say: "I'm sorry you feel that way, if anything changes let me know."

Good luck mate.

To Torquemadaza you listen. Wise is he in the ways of the Force.

Possibly . . . share your post with them with maybe a small amount of editing if you wish. 

Let them see what you are feeling.

My suggestion is narrowing down your group’s sessions to once or twice a week and encourage the other couple to seek out other campaigns to supplement the extra days they would want to have sessions. That way everybody wins!
