As the hand played out, I think this is an easy fold. Considering this is a rainbow board his reraise is telling you that he can beat a one pair hand. Anyways I would have called the flop bet and use your position to evaluate on the turn. I also think its OK to limp with AJ most of the time, but you should raise every once in awhile and thin the field. But if your gonna limp, you have to be willing to throw the hand away in a situation like this when you are under heavy pressure.
