She sounds like a candidate.
Your first step is to read all the MLC resourses on this board.
Smurf has them in one place, and there are other links, too.
Read what Snodderly has to say. While reading, see if you can identify any of the behaviors associated with MLC. No MLCer has every symptom, and all MLCs are different.
Read the first chapter of DR, then buy the book. The first chapter is here on the board.
If it is MLC, you're in a storm you just have to ride out. You can't fix it. MLCers tend not to respond to rational thought.

Don't freak out. Back off and take care of yourself. If this is MLC, it's going to be a waiting game. My attorney calls it 'emotional chicken.'

I'm sorry your circumstances bring you here, but if you have to go through this, this is a good place to be.
