I think you were fine. He may have had a big A and continued paying you off. Which is more likely than him hitting a set. And with what he did have even if he misses his set on the turn he may fire another barrel.
If you checkraise the hand is over on the flop. Let him try to give you more money when you are ahead. You have top two heads up against a raiser. Don't secondguess this IMO. He hit his 2 outer. You just didn't hit your 4 out redraw. This is just a bad beat, not bad playing.
A completely different situation where you see this same thinking: It's like the person who gets all-in PF with KK vs. A7. River A. Of course the 1st thing through their mind is they should of stop-n-goed and he would of never called the flop bet. While they're often correct that the person would not have called I think that they're still correct to get all-in there PF. It was still the right play.

I'm rambling...
