AQo is a problem hand, you'll need to define where you are early, or it'll cost you a lot like it did here.

Reraise preflop and if raised back at you consider folding.

As you played preflop on the flop you must raise. His bet is most likely a c-bet make him tell you the value of his hand.

On the turn, this is getting very costly and you still have no idea of what he has got, have you?

As you played the hand he might very well have JJ or TT thinking that you are on a flush draw that missed. You could have been way ahead from the flop.
