Fnord, you sound like you are on a limit game and the guy just reraised you one more big bet. How you can even contemplate a call in this spot is beyond me. Anything he is reraising you all in with, which is probably ~180 dollar call for you, is way better than what you are holding.

Your preflop raise was a small mistake. You bet the flop as if you were holding AK or AQ. Now you get raised AI---you gotta cut your losses on this crappy hand and move on.

Now, what would you do if you are holding AK in that spot? Do you call then? I'm all about pushing all in with a hand like AK with that board, but calling someone else's is a totally different situation. No fold equity in calling.
