Beth- I find it curious that you refer to you dad as your natural father. Only because my dad was adopted and refers to his mother and father as "natural", not "biological". My father's natural mother died when he was three, his natural father when he was 10. My grandparents adopted him at eight. I wonder if there is a generational difference, although I am sure you are younger than my dad (born 1953)? His biological parents had 3 sons, he calls them his natural brothers. He does call the one he has become friends with just his brother sometimes.

My friend's ex was also mad when she had her maiden name restored after the divorce. He is still controlling after the divorce and it just really angers him. I am like, jeez she didn't want you why would she want your name??
