Million Hand please critic

[zizazziza]

Alright, well I have been pretty tight at the table and been showing down good hands. The villian in this hand raises 3xBB with good hands and 4xBB with marginal/bad hands. My r/r was to make it so that if he called there was exactly a PSB left and I was going to shove the flop if he called. I was a little shocked that he called, but I put his range at AJ, KQ, KJ, low-med PP. When he called I figured that I might as well take a free card to hit my flush and if I hit it I will be able to double up and if not I can shove the turn. I pick up even more outs and decide to check again. Did I just play this hand to weak after such a strong PF play
