He checks. You bet $14. He raises to $45, and he hasn't raised all night.
You'd pay $31 for a final pot of $113, so you need to win 27% of the time. A player who never raises rarely does it with a worse ace. One pair is one pair, and you fold.
You lose the $25 you put in, and you keep the rest of your stack.
