Uh....what?

Guys have such a weird sense of humour. How is pretending to break up with someone because they're bored a joke? Also, I don't know if it's just me, but I don't think ex's should be super close to their ex's unless they have a child together or something like that. I have a friend who's boyfriend is getting all comfy with his ex. I don't think it's right. I would never let my ex lay on my lap and nuzzle my shirt while they tell me how bad they missed me. It's wrong, right?
