Allow me creative license as I quote your comment:
There is always a second side to things. You've already lost your Mom. Don't throw away your father too. His family is still your family. Sure they aren't grandma and aunts but they are step-grandma and aunts and still related to M. Parents are people too.
Perhaps you did not read the part about my father throwing me away. Perhaps you didn't note how I was given an ultimatum to treat his wife as my mother and her daughters as my sisters, or he would not be part of my life. Maybe you missed the part where it was directly dictated, "If I am to be Grandpa, then ****** is to be Grandma and **** and **** are to be aunts." You might have missed how I have been given no choice but to act as if my family of 30 years did not exist simply because he has a new life and that new life needs to replace all I've ever known. Not co-exist, mind you, but replace, per my dad. His family is NOT related to me or my family unless I CHOOSE it to be that way. And I could have very easily chosen it that way if I was not given the ultimatum of all or nothing--new replaces old--but that was not an option my father was ok with. He very easily replaced his wife; not so easy to replace my mom. And if his wife and I were allowed to be friends and familial with no expectation that she and her daughters were my "new mommy and new sissies" then things could be different. Those are all choices of my father, however, and I will not be moved.
You are right. Parents are people. MY PARENT was my mother. Dead or alive, still my mother. My father told me if I don't accept his wife as my mother and her daughters as my sisters, he was not my father. Who's doing the throwing away here?
As always, thank you for the opportunity to clear up any misconception that you or others may have had. I languished ALL day on Sunday about not calling or emailing or sending my father his Father's Day card. I cried. I worried. I prayed. I asked John if I was making the right decision by not contacting him. And you know what my very level-headed, arbitrary, impartial husband said? "His choice."
Sad as it was, it was his choice.
