Sorry for you CC, it really does svck when they decide to go that route... remember that because he was withdrawn and you were detached, this is as much as anything probably a ploy just to get some attention/reaction out of you. The MLCer doesn't really care if the attention they get is bad or good, they just want the attention, and if they can make you out to be the bad guy or the "witch" in the argument, all the better. Then they have validation for why they "Can't love you anymore."
Just remember, most of what they say is all BS. Try not to take it personal. Job's advice is good... work on being able to walk away and not engage, it's healthier for both of you. But I know from experience it is NOT always easy. You have plenty of things to be angry about yourself and it can be hard to walk away from an opportunity to let some of it out. :P
