I was actually in a similar situation just over a year ago. I had an argument with my father which ended with him telling me that he no longer wanted me to be his daughter. After that I stopped talking to him because I’d had enough of all the hurt that came with it, after all a 15 year old shouldn’t have to hear those words from her own father. A few months later however I got told that he had lung cancer after a lifetime of smoking, and that he would not be alive for very long. It was a hard decision whether or not to see him again, and I chose to stay away. Like your father, he had always been emotionally abuse, both to myself and my mother, and I felt justified in my decision. I can’t say 100% what is right for you, so I’ll ask you this. Do you think the pain that you feel when you see him will be worse than the pain of regretting not supporting him after he dies? If you feel it is, then you should definitely stay away, you need to make this decision with your own health and happiness in mind. Whatever you decide I hope it makes you happy, and I’m sending love and prayers to you to help you get through this. Just remember, there is no wrong or right in the situation, and if you choose to walk away now, you are still a good person.
