$25NL - AQo Cbet called, turn brings nut flush draw

Only have about 20 hands on villain and they have been fairly loose aggressive preflop, and passive postflop, but I havent seen how they respond to a cbet.

UTG+1 raise AQo to 4xBB, one caller.

Flop comes T high with 2 to a diamond flush and its checked to me. I make a smallish [a little more than 1/2 pot cbet] and he calls.

Turn brings another diamond and villain checks again, and I bet out and villain check raises me. The flop and turn line make me think villain was on a flush draw and hit, so I fold.

Villain has a near full stack, the immediate odds arent there for calling for the flush and I dont think my overs are solid outs so I fold. My main question here is what should my line have been? After looking back I feel that I should have checked behind on the turn for a free card, what does everybody think?

Check the turn. Fireing the second barrel with no hand should be a rare thing.

I'm a goof ball when it comes to stuff like this.

I rather check to the nuts, and bet if I had a Qd....

interesting....

But overall: Yes I agree with the check on the turn.
