Over the years there have been several incidents. But because the person is my husband's mother, I let him handle it. I don't want to get into petty "Jerry Springer" type drama so I don't.
A huge final incident happened about 7 years ago and we no longer see her. She is very verbally abusive to all family members and we refuse to participate in it or be victims of it. My husband told her that we would resume a relationship if and when she gets some kind of counseling. But she has refused.
