I'd rather raise the flop and call a turn checkraise if no paint hits the board. As played, I think you can go ahead to fold. It's clear he wanted you to bet b/c he knows you have a piece of the board or pair but he can beat that piece with his JJ or whatever. Dump it. But I don't like the flop play.

EDIT: Missed that you had gutshot so I guess you have to call the turn checkraise now. But I still think the key street here was the flop and, had you played it straight, the hand would have been better played.
