Very confusing hand, can I fold this river? Should I?

[Missile Crisis]

Villain here was like 45/12/4.5 and playing pretty erratically although he hadn't really shown much down. I was running pretty tight, like 18/14 or something.

I pretty much butchered this, but I think it's fairly interesting regardless.

Basically I didn't raise the flop because he was playing so erratically that I felt like he'd be likely to 3 bet with a lot of draws and put me in a really ugly spot. The turn raise is a no brainer but I think I probably should have made it larger. The river... ugh.
