Given the way you played it, I think you have to fold the river here. You still have 1240 in chips which isn't too bad. The pot was small, villain made a huge raise on the river. You gave him the free card on the flop to try to help his hand out. Fine. If indeed that card helped him out, then the river just beat you. I'd fold, though I'd hate it (unless you have a read that villain would bluff like this).

That having been said, I think you lead out on the turn with a bet and hope to get raised. Then you can come back over the top.
