I'm really struggling to manage the situation I am currently in and looking for wisdom from wise Mumsnetters. My mother is terminally ill, she has cancer and is not expected to see Christmas. We have always had a close relationship, particularly since my dad died when I was a teenager. I am the oldest daughter and I took on a lot of the jobs around the house after dad was gone while my mum retrained in her career to support the family, she was amazing. I have two younger siblings. One is overseas and is very low contact with the family. The other is the problem. He is an alcoholic. He is what you would call a functioning alcohol, I guess, except that he isn't really functioning - his drinking has made him a thoroughly bad tempered and unpleasant person to be around. His marriage broke up some years back and his teenage kids want nothing to do with him. My issue is with my mother. He has behaved terribly to her, to my younger sister and to me over many decades, and to his own wife. Despite all of the harm he has done to our own family and to his, my mother has never acknowledged that he has a problem and in fact has enabled him in many ways, by always picking up the pieces for him and basically mollycoddling him. I think she felt in some way that it was her fault that our dad had died and he suffered such a bad loss early on. But we all suffered that same loss and didn't end up like him. I long ago gave up believing that he could or would change, so that apsect of it doesn't bother me. But when my mum was diagnosed with cancer, I found myself filled with anger at her - like she never addressed this issue that wrecked our family, and now it is too late. My mother is a good person, but I believe this was a terrible blind spot which has far-reaching consequences for all of us. But the last thing I want is to spend her last months feeling angry with her. Can you help me get some perspective please? I'm so sad but I'm also so filled with rage
