Push this Overpair?

[Origami]

I know I played this hand poorly. I feel as though I should have pushed, but not sure where. I have absolutely no read on villain as this was my first hand at the table, but I felt as though he was trying to push me off my hand. His smooth call of the PF raise is either big cards/connectors that he likes but wants to see a flop as cheaply as possible, or a big pair that he is trying to trap with. What do you think?
