Maybe try to find an Adventurers League location where you live now? They are a bunch of one shot adventures instead of a campaign so you can play until you move without joining a campaign and then leaving the campaign when you move. 

Doesn't sound like you would be thrilled to play, so don't.

If commitment is the issue, I would look for very-low-commitment games, like one shots over Skype or Discord.

If you do not mind playing by yourself and have played Betrayal at House on the Hill board game (there is also Betrayal at Baldur's Gate , a D&D themed version of the game), you can borrow its exploration mechanic and create a simple dungeon crawl experience into a haunted house. No DM or other players are necessary. Depending on how much you want to incorporate the boardgame into D&D, you will have to do more rules tweaking for the board game, and probably require another player or DM if you are incorporating a lot. If you are just incorporating the exploration mechanic, then there is not really much to adjust outside of determining how big the rooms are and how monsters and items spawn.

I will give you a hint about being the DM. We all learn how to DM on the fly. I made tons of mistakes and I still make tons of mistakes!

If you don't love the idea of DMing, don't do it. DMing is a lot of work and takes a certain type of temperament.  So if you just want to be a player, that is what you should try to be.

I don't have any real advice for you on how to find a compatible group. It's a shame there isn't a "Match.com" version for D&D. You put in your favorite edition, favorite types of adventures,  preferred play style, favorite setting, whether you want to DM or play, how often and when you like to play, etc... and the site matches you with other people who gave compatible answers. But unfortunately, as far as I know, those kinds of sites only exist for romance.

Absent that, the best suggestion I can give you is to see if you can get your existing circle of friends to play D&D, rather than trying to find strangers who play D&D and with whom you will be compatible. All you need to have is 1 person in your circle who wants to... and if he or she has 1 person in their circle not in yours, who wants to... and so on, and so on... you can maybe get a group together.

But fair warning, the guy who initiates the "let's play D&D" thing usually gets tagged with being the DM... so... not sure how well that will work for ya, since you don't want to do that.

You could get involved in some online communities (like this) and get to know people online and then invite them to game with you.

D&D is definitely a game it is hard to really learn how to play without actually playing it. You can gain a little from watching others, but it's not the same thing has having to make sense of all that stuff on your character sheet for yourself. Much the same way you couldn't actually ride a bicycle by watching someone else do it or reading books on how to pedal.
