Final Pot: t1245

After he calls my pretty big re-raise, I feel like I have to put him on a large pair. With the flop that came down, I feel like I'm way behind almost any big pair. KK and AA are obviously bad, and he's made trips with 10's or Q's. Anyone feel I should have bet the flop here or pushed pre-flop? I just felt like I could find better hands to risk all my stack with, and by bailing now I've still got half my stack.
