I think you made the right play here. There is little chance he's bluffing you on a draw or worse pair, and if he is you must have an extremely solid read on him to make this call. In my opinion he has something like AJ or A10 suited and got a feel that you weren't holding an ace in your hand on the flop, therefore he had the best of it and pushed in on you. Should you have bet larger on the flop I'm sure he would have at least called you down to the river with his hand if not reraised.
