I would fold. There is a chance that you have the best hand, but there is also a chance that he stumbled into a better hand than you (two pair or a small set) and quite frankly its just not worth risking that much money over without the flop making you a clear winner. Besides, it seems obvious that this guy is going to give you his money sooner or later anyway, you had might as well wait and pick your spot.
