I am new to this so I am sure someone has a better idea of what to do here but i think you lost total control when you didn't bet the flop. I would have bet the flop to see where i was at especially since I have the chips to do it. If he goes over the top again you have a tough decision but he may have AK he may have pocket AA, KK, QQ. You have no idea where you are at now though.
