Tricky spot with JJ in 3-bet pot. 50nl.

[Debaser]

Villain was 36/5/1 over 150 hands. Obviously I was happy with the flop but his bet kinda surprised me. This is just one of those spots where everything feels wrong. If I push this is a bigger pair every time and folding to a 1/2 pot bet is soooo weak. If I call I have 1/3 of my stack in and every turn card sucks.
