$100NL AQ hand, good fold?

Its 6 handed, Villain has $110, I have him covered. Villain is a solid player, he may be slightly on tilt after I busted him with my straight on the river a few hands ago.
Folded round to Villain on the button who raises to $5
I call in SB with AQ, BB folds.
Flop is A 10 3 rainbow, he bets pot I call. (Maybe I should have raised to see where I was?)
Pot is $35, turn is J.
He bets $25, I think for a bit and fold.
My reason being, I only beat a bluff, or possibly A8/9. Good fold?

Also any comments on my posting style are welcome, I'm not sure how clear/well explained it is.
