NB....
I'm sorry about your sister.......mine doesn't have contact with me either(unless it benefits her)...
All I do is remember is that it's HER choice not mine...although that makes me irritated too......time helps...and you never know about the future.....
AND I'm waiting for my chance to tell her and her idiot husband exactly what I think. But out of respect for my parents, it'll have to wait....
hang in there...the best revenge is to live well in spite of them.....then it's proven that those of us that leave the organization can function and not lose ourselves.......
