Wait, so you're asking a forum community that you joined up with yesterday if you should marry someone who we don't know. Gah? Logic people, logic. The 2 in the title should have given me a clue.
I have an odd feeling that this OP is lying though. Nobody goes 'I'll tell you yes or no right after I check what the Escapist thinks'. And who would be stupid enough to ask for marital advice on a gaming forum from people that you don't know and that don't know you or your boyfriend? Nobody, that's who.
If you are serious about this than I advise dumping him. You've been going out for a couple of months and suddenly he wants to marry you? Most teenagers don't want to get married. I suspect ulterior motives behind this move. Maybe he wants to get you in a relationship which you will find more difficult to leave or maybe he's a s thick as rocks and twice as stupid so thinks marriage is a good idea. Either way, fuck him.
Nobody ever takes my advice though, and for good reason, as most of it is 'dump em'. It just sounds like he got caught up in a moment. Say that you don't want to get married (if that's how you feel, I'm not in your mind) but want to stay together (if you want to, that is).
