TPTK/nut flush draw on the flop

[jds1201]

Typical Party $25NL table. Villian loose/passive with about a 60% VP$IP and post flop aggression 0.75. I liked my hand on the flop with TPTK and the big draw, but when he called the big raise, I thought I needed to improve to win. Villian was easily capable of playing any two suited cards. I thought he could either be trapping with a made flush or have a baby flush that he though I might have beat, so I didn't consider making two pair on the turn to be a big help.
