My own fault or just write him down as a fish and move on?

raise more on the turn, plenty of draws can make it on the river, though he made it easy on you letting you check behind on the river. He obviously liked his hand enough to call the well-sized flop bet so see just how much he likes it on the turn.

Also, a ch/r on the turn leaves you with an easier decision if you bet larger.

Bet 10-12 on the turn. He'll raise there if he has you beat and will probably fold a flush draw.
