Flop top two with flush draw on board - how'd I play it?

[kt421]

Dug this out of the PT database while doing my first real review of my play. It hasn't been very pleasant, as I'm learning that I don't play very well, but perhaps I'm on the road to improvement.

How would you play this? Sorry, no reads - old hand.

Final Pot: 13 BB

On the river I knew I was beat. I'm wondering if there was a better line to either (a) get out quicker or (b) have a better chance of folding Villian. I also suspect that I should have raised pf, but I don't think that would have pushed him out (or would that even have been the reason to raise?). Thanks for any input.
