When was the last time you saw her before this visit to her? Has it felt like things have not been good between you for awhile? I know I did not tell my mother a worker in our household assaulted me until I was grown/20 years later and then only vaguely. I did not feel angry at my mother though, like it was her fault. The worker was part of my parent's life for 3-4 years after he assaulted me and I just worked hard to avoid him. I can see how one could feel angry at one's mother but still, something feels off about the whole thing, not like she is lying necessarily but more like she is focused on being angry at you rather than solving the "problem" -- almost like she is using the situation to be angry at you. How does she feel about her father and your divorce?
