I don't know of any family that doesn't have issues. I'm not exempt, I haven't seen or had words with my sister since 1989. She thought I was the "Favored" child. There were no favored children in my family. I just overheard the arguments my parents had with her. ( I couldn't help but not hear them) I just didn't do what she tried to get away with. She, on the other hand, didn't see it that way.
I had an uncle that thought it was just horrible that I wasn't in contact with her, and told me so. He never knew that I could have given her everything I had, and it still wouldn't have been enough for her.
Bottom line, you have to play it by ear. As much as you'd like to come out to family, it might not be such a hot idea.
