By my way of thinking, as I am socially, financially, educationally equal to my STBX husband, in no way did I ever feel that taking his name was a sign of giving ownership of myself to him.
Rather, at the time, to me it was a very romantic sign of love and full commitment to him as his wife. Now, to me, it means we are united in the same family under one name. We are "The H---s."
And I guess that another reason, perhaps the biggest reason that I don't want to give that up is because my married last name IS my new identity as part of my family. I still am a member of my family. My children and I are a family.
I don't want there to be a question in a hospital room, or when dealing with a billing or banking issue, or at school, of who I am in relation to my children. Having the same name as them is of social benefit; whether right or wrong, when people see that I have the same last name as my children, I am likely to be questioned less about my proper role.
I earned the right to change my name to my married name, the name of my children. I refuse to give it back. I will always be their mother.
Heck, this conversation has me thinking that I will never change my name for a man ever again, since I will never have another man's children. Any man who loves me will know how much my kids mean to me and will understand how I value carrying the same last name as my sons.
To love is to value. Only a rationally selfish man, a man of self-esteem, is capable of love—because he is the only man capable of holding firm, consistent, uncompromising, unbetrayed values. The man who does not value himself, cannot value anything or anyone. --Ayn Rand
