I've been to ex-boyf's weddings and am facebook friends with some exs! Actually, I'm Godmother to the son of an ex and his wife (a good friend before they got together).

I dunno. Living together and a month later he's over you - that is bad, no matter with whom it is. Dating and moving on - it happens.

If it is AFTER a breakup, I don't have a problem with it. May be upset if he got over me so quickly but that's cos he's thick. Obviously he's thick, I broke up with him!
