I guess my line of thinking was:

1) What kind of hands would this guy cold call a preflop raise with?

2) What hands would he be willing to raise with? (on the turn given the board and action)

3) Which hands that fit 1&2 can I beat?

Based on this I figured 'not many' and folded given the pot and action. Is this LINE of reasoning jacked or is it a wrong decison based on decent reasoning?

My assumptions were: a PP would reraise preflop (TT or KK in particular)

2 pair was not a possible hand to be against.

Turn card helped this guy--how else could it help other than by the 3 flush on the board.

Bad assumptions? How would you approach this?
