AQ reraised, deep, and oop. FUN!!

[GTL]

I have been 3-betting preflop a decent amount. Villain has been opening fairly light and up untill now has generally been folding to my 3-bets. He has called them maybe once and then folded to a continuation bet. Villain has been playing solid and we have only tangled in one large pot where he called down a 3-barrell bluff with top pair queen kicker on a fairly scary board.

This is such a tough spot for me on the turn. I'm not sure I like my bet size here or even like a bet at all. When I made the bet I decided to shut down if it was called but I'm not sure this is the best line here. Comments on all streets are welcome.
