Most Helpful Guy
the fact is if you legitimately want to try things with him there is no point in setting some deadline. it's controlling and useless. You can simply not wait on him but when he gets back into town, what are you going to say oh you moved back later than you said I don't want to talk to you? If you truly care about him then you should want to give it a shot rather than set some arbitrary deadline.
Moving back may be a bit beyond his control. So I would just continue with your life, not wait on him but not give him some deadline to move back. If you meet someone before he moves back then that is his loss but if you don't and he's moved back you don't want to have alienated him with a deadline
