I had TP now I dont

[inferno]

Villian seems to be reraising me allot preflop which is annoying, other than that I have no perticular read on him. I woudnt call him a super fish.

I get KTs MP I raise, villian 3bets in the CO rest folds
Flop comes KQ6r
I check and he checks behind, which is weird
Turn comes A and also put a flush draw on the board, I check and he bets, I ... call down or is this the easiest fold ever.
