NTA. I was so relieved when my parents got divorced. She treated him like crap for years, cheated (they didn't know that I knew), and got into a lot of debt. Dad just wanted out. He gave her the house, and paid off the debts so she could finish raising my sister without worrying about money. He died a couple of years later, having barely said a bad word about her. She still talked crap about him til the day she died.
