I always said I would never change my name as I really like my last name. But he was adamant that he wouldn't take my last name and I really didn't want our son to have a different name to me or his father.
So I decided that I would change my name but I really really disliked his last name! After much discussion we decided that we would both change our names! His father was an a*hole and walked out when he was little, so to have a name the same as him (his parents were never married) didn't make sense anyway. He's kept the name as an additional middle name anyway and he's changed his surname to his mother's maiden name - which we both like.
I will keep my surname as another middle name and take on his new name. Unfortunately we couldn't double barrel as my surname doesn't go with anything!!
