That's the problem with labeling someone with MLC. It gets you into some kind of mindset that you have to pass through a certain number of stages and there is nothing you can do about it. If it turned out she had a treatable depression you'd feel silly later that you were waiting for the MLC to work out. Personally, I'm not real fond of that designation. I've seen it used here for all kinds of people, even ones with a perfectly good reason to walk away, like their spouse was an a$$ or they are having an affair.
