I think you got off cheap on this one. You checked behind when he was certainly going for the c/r after making the 2nd nuts at the river. Played well IMO. You gave him poor odds to chase at the turn. He paid $6.00 to win $6.50 after calling your turn raise (correct odds would have been about 3:1 and he paid 1:1ish). And then he gave you a free showdown. VNH even though you lost.
