mehh, I don't like this either.

he c/c flop and turn. What's his handrange? Seems to me he's either calling this flop w/ a Jack, a Ten or some kinda draw. The same for the turn.
Because you said he 'isn't horrible', he probably wouldn't play a busted draw like this. His c/c on flop and turn and then leading out on river seems like a pretty big hand.

This rivercard is a blank, and he certainly doesn't believe that this 3 helped you in any way. That's why he should make a big laydown w/ a Jack or a Ten.

Turn is not a real good card to second barrel imo. I'd just give up the hand on the turn. Since you have a pp, you always have a bit FE if he could be drawing.
