((((Indy))) I know how you feel. I have a similar relationship with my eldest half brother, and I disengaged from him after a minor betrayal. My father constantly tried to get me to become involved in his life and problems. It's really hard to say no, but you have to care for yourself first. Some people are just trouble. They will drag you down if you let them.
I also feel guilt, but I know it's better than dealing with his issues.
