I got lost in this spot.

Preflop - no questions about it.
Flop - hits top two. After he checks, I decided to really think v-bet from KK, AK, maybe KQ. After this raise - should I 3-bet or just call?
Turn - the plan was to flat his raise and calldown if nasty cards won't show up. The problem is that the king of hearts is the worst card in the deck i guess. His check was kinda weird but I decided to pot control.
River - I couldn't fold there. This was a really weird line. In fact after his check ott he didn't represent to much. His sets and two pairs should bet then to protect and gain value from my FD.

What do you think about this line?
