OOps -- wasn't clear, sorry...it began a few weeks ago and since then we've seen each other a few times, for sex purposes only. First time he had a girlfriend and it was drunken and kind of random. Then he broke up with gf (had nothing to do with me, he had been planning to for awhile but was just waiting for the right time, whatever that means!) and continued to see me on the sly. My brother would absolutely freak out on both of us if he found out. Anyway, I'm not quite sure he likes me, so I've simply resigned myself to the fact that no, he probably doesn't. It's much easier that way. Besides, I think this is all part of my own rebound (bf and I split a few months ago).
Man, when did I get so stupid?!
