<human>: I'm 22[f] and he's 25[m] and we were together for 9 months (officially, but I suppose unofficially it was a year and some change). At the beginning of August I moved to a different city (only a few hours away) for work. Then about two weeks ago he dumped me under the reasoning that "he just doesn't want to be a in a relationship anymore" but "still loves me" and "wants to get back together soon." He claims there are no other women or anything.
He said that he wants me to wait for him but I don't understand what I'm waiting for. If there's no one else, then what am I waiting on him to do? He's not moving down here with me  anytime soon and he's basically stopped talking to me. Honestly, on top of being hurt, I'm starting to get angry and will soon end up resenting him. 
I'd like to think that it's the sudden "distance" that's just stressing him out. And if it is something non-detrimental like that, I'll wait for him to figure himself out. But how long is too long to wait?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Ex-boyfriend dumped me for no reason, says he wants to get back together but isn't acting like it. If I should wait on him, how long is too long before I should move on?
