Gimme a line to replace this atrocious play

[GoCubsGo]

Just when I thought I was pulling it together and playing pretty well, I do something so dumb. Villain is 6/3 with no postflop agression after 65 hands. Haven't seen him show down any hands.

Final Pot:

I bet half the pot on the turn because I didn't want to get it all in on the river. But then on the river the pot is $97 and he only had $65 or so. I tried betting $30 as a blocking bet but then had tremendous odds on his raise, which could have been from a PP lower than kings very rarely, but still often enough to make the call profitable. The turn action is really important, and I'm not sure what to do there. Please help.
