Seems like based on your information that you should try quizzing him about his hand since he was helpful before. In absence of any other information you pick up on from him, I would do whatever you think is more likely to get all the money in the pot (push or call). Why would he raise like that if he hit a set? Two pair seems unlikely but not impossible. Looks more like ak or kq or who knows in a live game, but I can't fold this for these stack sizes.
