If she follows you to wherever you are in the house/seeks you out, then do not be there when she comes. Think of like this: you're in a really deep pit, and you are trying to climb out on a ladder. Every time she says "I'm done" or something like that, you fall a few rungs (or a lot of rungs) backwards. You're not getting anywhere because you're giving her total access to you. Didn't we all talk about facebook weeks ago? You said you'd think about defriending/blocking. Have you done that? It's like you're saying "here I am, hurt me some more" by being there, by answering all these texts, by seeing her on facebook, and whatever else.
I don't want to come off as mean but I guess this is a 2 x 4 from me: I don't see you doing one thing to protect yourself from her onslaught of criticism and craziness. I don't think you're believing those of us who have been through this and who know the way this MLC stuff plays out. You're putting more trust in HER to "save" you from your pain than in the collective experience and wisdom of the people here.
That is, of course, your choice. But the consequences of your choice are terribly detrimental to your emotional health.
She hurt you when she left you, but you're hurting yourself the most right now. I know that's hard to hear, but inability to detach is a form of self-hurt, and it takes a conscious effort from you and only you to detach and insulate yourself.
