People in crisis whether is be a wayward spouse, MLC, milestone crisis, just done trying in the MR...whatever, are like caged animals. They will do anything, say anything, manipulate and behave in completely out of character ways to removed anything in the path between them and what they think will make them feel better. You are a person in that path. As personal as her behavior is to you, currently in this moment what she's doing isn't personal. It has absolutely nothing to do with you. Which is why every one keeps saying stop focusing on her focus on you. She isn't focused on you so why are you wasting all this time and emotional energy on focusing on her?
