the hand has played itself - neither of you are getting away from it, and he has lucked out with his 1-outer. That"s poker.
I would have made a pot-raise preflop though - knowing you can"t push him off a hand preflop is irrelevant... you have a really strong hand, and given that he is likely to call you with any rags, a raise is even more important. Pot preflop, and c-bet pot blind on the flop.
