[Cry Me A River]

I think you got about as much as you could out of him here. Villains will sometimes call cbets after obvious blind steals pretty lightly hoping you'll give up on the turn and they can take it away from you, or they hope to improve, or they figure they likely have the best hand. So he may be calling that flop bet with any pair or a naked Ace. Your check induces him to take a stab at it, but once you show any real strength he's not sticking around.
