Breaking up?

So the guy I mentioned going on a date with before became my boyfriend. We've only been dating a couple weeks. I wanted to wait to tell him about my being bipolar until we had been together for a while, but something from my past came up and he said he wanted us to lay all our cards on the table. He would share all of his baggage if I would share mine. I had more cards. He said he needed some time to think last night after our conversation. I made him promise that he would break up with me in person if he was going to break up with me. He called me this morning and said he wanted to come over for a bit this afternoon to talk. I think this is it. I think this is him breaking up with me. The really sad thing is...I really liked this guy. It sounds so stupid this early in our relationship to say that, but no one has ever treated me as good as he has. I mean he had all the other guys beat at day one. Every asshole I've ever been with has shown his stripes from the very beginning and I was stupid and dated them anyway. But this guy...he's different. He's a gentleman. He hasn't been pressuring me for sex (which you'd think any decent guy wouldn't at this point, but every other guy I've ever dated started pressuring after our first kiss), he calls me beautiful, he tells me he's happy he met me...these are all things I really should be expecting from ANY guy, but I just haven't been able to find them until now and I'm not ready to give them up.
