DS1 is 11 he is my DH step son. I was not married to DS1's father, our relationship was short and he did not want any kids but I refused to have an abortion, anyway when DS was born he was happy to acknowledge him as his and I wanted his name on the birth cert. We split when DS was 8 months old because he was not able to cope with the responsibility of having a child and I got fed up with being the only adult in the house. My relationship with DS's father has been strained over the years - difficulty's with maintenance payments and some other nastiness that I don't really wish to go into.
DS has always had a good relationship with his dad regardless of my feelings about him. He sees his father nearly every fortnight.
Anyway, I got married three years ago. DS1 still has his fathers name but I have taken my DH name. Recently DH has been suggesting that DS should change his name to my maiden name. He feels that DS1 having his fathers name is an insult to me (DH knows our history and strongly dislikes DS's father because of what he has put me through) and that DS having a name that is not related to either of our families is unnecessarily complicated, especially as DS's father actually contributes almost nothing to his life and shows almost zero interest in him.
I don't want DS to change his name. I can't be specific as to why, I just feel that its not right. AIBU?
