Two pair with three hearts on the board

[gito]

I had played 40 hands until this hand, villian sucks preflop, playing 2/3 of his hands, calling raises with Q6o and goes to showdown about half the time.

Is there a leak in my play? Is calling the right thing on the turn? What should I do after getting raised?

I think based on the way he plays, he can have weaker hands like Kx, K7, as well as a flush.

Still I don't know what to do.
