200NL - Two pair gets 3bet on the turn, standard fold or weak?

[Clever Nickname]

Villain in this hand is 19/15/infinity over like 40 hands, I haven't seen him get out of line yet. I feel like his 3-betting range is crushing me, and his bet sizing makes it look like he definitely wants a call. Still though, I thought I should get some feedback on the hand, because it does feel a bit weak. Does anyone advocate taking a different line at any point? I know my turn raise is small, but I'm not really afraid of any draws and I want to keep him in with strong one-pair hands.
