The game hasn't even started yet, but basically if I don't play, it's possible that it may not run at all
That would seem to be a reason for the DM to run something else, if it turns out to be true, but is still not a reason for whiney behaviour. Once you've made your pitch, and the DM has responded, then do what you think is best (play or not play) in a friendly way. If that means someone else has to run the game, so be it.
That's pretty much all the social obligation you have.
