20NL 6-max line check

I just would like a line check and analysis into what to do on river.
The villain in this hand (the button) is the guy who I won my stack off of and seemed to be entering every pot that I did. It was clear that he wanted his chips back and was somewhat spewing against me...

raise more on the flop (3,5) and bet the pot on the turn. i like a check / call on the river. if he shoves all in on the river, well you have a tough decision, but if you think he is tilting a bit don't lay it down
