I am so sorry your adult children have alienated you. My adult children are very angry with me for leaving their father six months ago. My situation is not as bad as yours as my children still invite me to birthdays, etc., but their father has cried on their shoulders and painted a negative picture of me to our children. They have said they blame me and are angry with me. They have no idea of the years of emotional and mental abuse I have endured from their father. I am just making sure I reach out to my children and keep in contact with them as much as I can. I have faith they will see that I am the same mom who has loved them and will always be there for them. Reach out to your children. Let them know you love them and that the divorce/separation has nothing to do with them. Adult children should be mature enough to understand that they need to remain neutral in their parent's relationship. Unfortunately, that is not always the case. Good luck. I'll be thinking of you.
