My husband did exactly the same. In the heat of an arguement i said if that's how you feel then i'll pack your bags. Ten minutes later i said i didn't mean it, but he took it as his Q to leave. He also insisted that i made him go even though i said i didn't really think it was a good idea. He's back again now, we're still wading through mud, but at least he's here. I must say they can be very clever, putting the blame on you, because they feel guilty. Let it go over you head. sounds like you're keeping your cool.

Good luck
