50nl 140bb deep, bet into on flop with gutshot SFD

<font color="blue">Villian is 17 / 11 / 13 over 85 hands</font>

I don't really know what i thought of his bet into me, but i figured if he had a set and i raised him to 10 he'd repop to ~30ish putting me in a very tough spot..

How do you play this hand from here

Note: Once again, im currently in the process of moving UP to 50nl, so i may not play for draws as aggressively to begin with
