Stop worrying about putting a label on it and start putting together a plan of action. Your W is an active A and you seem to think if you label MLC she will snap out of it and come to her senses. Wrong!
You mentioned setting boundaries? What are they? What are the consequences for breaking them?
If you want to turn this around you need to take massive action!
Are you exercising? Reading self help books? Getting out with friends? Seeing a therapist?
