Lol this sucks.. from your description and the line you used, he must be pretty sure you have a so-so hand that can't stand pressure. So he could just shove you off of it. Ofcourse he knows that you know this, so could be for value too. So what I'm trying to say is, he probably knows what kind of hand you have (a one pair hand), while you don't know what he has since he's prolly shoving a good mix of bluff and value here..

I probably fold though because, thought processes aside, the board simply leaves too many options open that beat you..
