Sorry, but that doesn't make him a grandfather anymore than marrying the woman in the first place made him the daughter's father. My ex may remarry, but that only makes that guy her new husband, not my son's father, and nobody feels that more strongly than my son.
The whole premise to all this is that the titles given to a person involved in some woman's life are hers to bestow with no concern for biological or social reality. Too many women think they can define and re-define these things according to their latest romance.
Well, maybe you should tell that to the kid because he calls my brother "Grampa." I guess I never had a grandfather either since the only grandfather I ever knew was my widowed grandmother's second husband. They were married before I was born, as well. You can KMA because that great man WAS my grandfather, regardless of your "holier-than-thou" definition.
I may not be the father (sperm donor) to my wife's daughters, but I certainly am Daddy. I've been more a father to them than their sire ever was.

My stepfather and my father are two great, wonderful grandfathers to my children. My husband is my oldest two's 'Daddy' to them and him. Love can go beyond blood and I'm sure glad because their "real" father is a sonuvab*tch.
