Exorcism. That's what the priest told me. He apologized, profusely. When the priest told Mom that I was not possessed by the devil, Mom changed religions.
I have come to believe she has a personality disorder and she will never get any better. I have lowered my hopes for our relationship. It is the way things are, and she goes blithely off in her own little world. Like you, this set me up for a great deal of unhappiness. I hope that the young lady in the program learns that her mother is never going to change.
