2/4, J8s trips on flop, my plan fails

[Endlestorm]

I have been playing LAG and getting a lot of respect. Most pots I raise I get one caller and take it down on flop with a pot-bet. I had a big stack two hands ago.

MP is 30/12ish. When he raised the flop I felt it most likely an overpair, which would not call a push. So I called planning to check/push the turn. However he checks behind. Ooooops. What do you think?
