I am so sorry, Tomi. Sounds like what my brother was/is doing to my parents.
The way I look at it, life is too short as it is. We've all made mistakes, but I have never lost contact with my parents. When they're gone, at least they will know that regardless of the issue, I love them and appreciate them.
Same goes for my other "mom" as well.........*******hugs*********
