Not to get too much into it, but my mother is one of five children. One of the sisters estranged herself from everyone. Then my mother went No Contact with them, too (cutting my sister and I off from everyone). Since FaceBook, my sister and I have a little contact with my moms family, but we arent very close. Theyre not awful people, IMO. Theyre regular people with personality flaws. My grandmother was supposedly a toxic narcissist, and so was the aunt who went No Contact decades ago. Heres the twist: My mother, frankly, is toxic, herself. She does the things she claimed THEY did. Sometimes the person leaving the family behind is the one with the problem. AND its an abusive technique. If you can manage to alienate your intimate partner from their family and friends, theyre more dependent and easier to control. ABUSE 101.
