Raise preflop 1st time. As played calling the PF raise after the limp is fine, basically intending to hit big or let it go.

I think you have to fold to the flopbet. You have to expect he will bet big on the turn also, and if you didn't hit you'll have to fold. So, you're calling for one street here imo, and not getting enough odds - esp since it's unclear he'll pay off if the flush hits.

Edit: I don't like a raise because it's a semibluff and i don't see enough fold equity here.
