I don't know. I hate FB sometimes. I can see it both ways. It would freak me out and make me back waaaaaay the eff off if I saw this on someone's FB after one date. But then I see it the other way: what if FB didn't even exist and he was telling all of his friends about me in the relationship context? I wouldn't be any the wiser. So FB sucks. It's actually ruined things for people just because they can see other people's neurotic behaviors that would otherwise be kept under wraps, haha. I mean, you know? I'd wait it out a little bit. Chalk it up to him being a little trigger happy and give him another chance.
