I've reached the point where I'm considering stopping all communication with an adult sibling. This person is selfish, has anger and alcohol problems, and treats family members poorly. I've finally had enough and could care less if I ever see or speak with this person again. I'm sure it will be upsetting to my parents, but I'm not like them. I refuse to keep tip toeing around this sibling at every family event and in my daily life. I don't want my children growing up thinking that the sibling's behavior is normal and acceptable. Just wondering if any of you have had a similar experience.
