I too can relate.....it is the hardest thing in the world to be abandoned by your parents.
I know for years I wanted my mother-I was so jealous when I saw other women and their mother's having this bond that I couldn't have. It is sad, I have come to the acceptance that my mother is in a way "dead".
I also know that I really yearned for a mother in my life. There were times when I wished that I could find an "adoptive" mother and live happily ever after. I do have a woman in my life that is my surrogate mother. I never knew how great unconditional love could feel. My children call her grandma and she comes from out of state to visit me. It amazes me that someone could show me such love when my own flesh and blood just tossed me aside.
I have often thought what would happen if the borg suddenly decided to "revise" their "rules" about associating w/df'd or da'd family members. I am a forgiving person, but all trust has been lost. I believe it would be very difficult for me to resume a relationship w/someone that cause so much hurt and pain in my life.
I look at my three children and can't even imagine walking away from any of them.
