HRW, the number 1 question is how is she with the kids? Does she behave as badly with the kids or just you? How old are your children? How ofen do you have the kids and how often do you have to have contact with her. You can set up some boundaries and keep conversations only about the kids and don’t let her drag you into anything else. Hang up, cut it short, or walk away. Do not try to reason with her about anything, do not think you can get through to her about anything,They can only think about their needs and no one else will ever matter. Has anyone ever called her on or noticed her behavior other than you? What does her family have to say about it? Do you have any support from your family or friends. Could you give a little more information about her behavior and who left who. Mine is Mr Wonderful to the outside world, no one would believe me if I tried to tell them, you have to live it to know what they are like. If possible, find a therapist that knows about this disorder and maybe they can help with what you need to tell your children, at some point they will need to know, there is nothing wrong with them.Do a search for therapist that specialize in personality disorders in your area, many are not qualified to help us, even interview to be sure. There is no help for a narcissist. There is nothing wrong with you, keep that in mind when you have to be around her. They have a way of making you feel responsible and guilty for everything. I am here if you want to share more. You are not alone, in this, others know exactly how you feel. Hugs mamolie
