Flop I think I should have reraised bigger, possibly .90-1.00

Looking back I'm not sure I should have checked the turn...

And again looking back I want to call the river, but what do you guys think?

Looking back I think he's mostly got single pair tens in his range, possible KT or TT,44,22 which is really the only thing that beat me unless he's floating me with a king. I guess that's the thing that confuses me about this hand, is how often do you guys think he's floating the flop with a king?
