Am I playing too weak?

[WSOP Bound]

I have no real reads, but PT indicates that this user is LPP after 18 hands. UTG Stop-n-go felt like a flush draw, but I think I'm giving him too much credit. Even if he showed me the flush I couldn't fold the turn so there's no question this is a call or raise. Should I have raised the turn and called down if rereaised?
