Given the size of the pot vs the size of his stack, I assumed that there was no way I would fold to a $7 re-raise w/o getting us both committed. Any re-raise would have basically committed us both to the pot because of his stack size. So, for some reason I just waited until the turn so that I could make sure and get the rest of it in in case he was ever considering folding. Now that I look back, I think I should have just re-raised him and let him either fold or push on me and I call.
