Call down mode, too weak?

[meow_meow]

My read on villain here is that he will raise flops with weak hands and draws, wait for the turn with a real hand. Given that, I'm not too happy with my play here, it seems so weak, yet I find myself falling into call down mode so often when I'm raised on the flop.
