Oh fur, gosh I completely understand.
I would say similar for myself. After a horrible ball busting, drag em out, dirty divorce my oldest daughter (age 17 at the time) took a turn for the worse. She started to physically abuse her younger sister and myself. It got so bad I kicked her out. I could not take her abuse any more. Fortunately we have made amends and she is back to being the lovely, beautiful, kind hearted young woman I know I raised. She has been told she can never live with me again. She has no relationship with her sister sadly as they keep each other at arms length. Her life path after leaving has been rocky but she has managed to find her own happiness, she is safe, and I am happy for her. I miss her dreadfully and we have a mutual agreement that we know we are there for each other.
