Comfortably in the money...then this hand comes up

[ShadowNC]

I think this is the first hand I've ever posted here though I read this forum just about every day.

This was from the Empire 5K last night, about 40 players left, top 30 make the money. I believe the avg stack was approximately 3500 at the time. My feeling is that I don't care about squeaking into the money, I want to make final tables. I felt like Villian might be trying to steal with a flush draw...with that in mind, how was my push here?
