What should I have Done?

I havent been playing for too too long, but i have a general strategy. I'm a tight aggressive player. So heres the shortened version of what happened.

I'm in the BB with pocket Kings spades and clubs). Blinds 50/100.

UTG + 2 raises to 550, I re-raise to 1100 and get to heads up with the raiser.

I bet 500, he calls and the turn is Ac. I check and he bets 2,000 into a pot of 4,500 and then I fold.

Since he preflop raised so much I put him on A-something and then the A came I didnt want to chance it. Do you think it was the right move? Think i should have bet more after the flop?
