I cut my mother off a year ago. I think she is vile. She is the only high energy, able bodied, college educated adult I know who gloats about being chronically unemployed. A job is beneath her and causes too much stress and chaos!

My working class grandparents sacrified to put her through college. She got pregnant one week after graduation on her wedding night and never used her degree. She was always "so busy" taking care of her 2500 square foot home on 1/4 of an acre--so much work.
She emotionally abused my father. She manipulated him into letting her stay home for 50 years of their marriage while he worked insane hours and ruined his health due to the stress of it. Her motivations and manipulative behaviors became crystal clear to me after he died.
My mind is more clear as time passes. I should have cut her off decades ago--she enjoyed kicking people when they were up and when they were down.
She threw her infant sister out of a moving car when she was 7 and said not one word as the car drove off. She wrote about it in a family "memoir" she gave to dozens of our relatives as though it was no big deal.
Her doctor said she could live to see 105. I will be close to 80. I am not wasting the next 30 years of my life tolerating her b.s.
With people living longer lives, I suspect parent cutoffs are becoming more common. If you have an emotionally abusive parent who lives to see 105, it makes zero sense to maintain a relationship with them just because they are your parent. Why do I owe my abusive parent 60 years of abusive contact in my adulthood just because she cared for me in my first 18 years?
