I get that there may be situations where relationships can be repaired because they are at their core good but circumstances have ruptured them. However, having a cruel narcissistic mother who still makes me feel like nothing even at 50 years old with a swag of achievements is not a situation that is capable of repair. After initially cutting contact I had to re-establish it when my father became terminally ill ( I had remained in contact with him). The result was a careful managed set of boundaries with under the pretence of a relationship. It was exhausting on my part and in the end made no difference. In the end I had to cease contact for the sake of my mental health and seek support from people who value me for who I am.
