I legally changed my last name to a beautiful old name on my mom's side of the family. I never felt even an ounce of connection to my birth name or my dad's side of the family. It hurt my parents when I did this, and I did feel rather sad about it. But the name I created for myself just felt incredibly right.
My husband got angry when I said I wanted to keep my name when we married. I sat at the courthouse writing my old name and new name over and over again, and to do this day I mourn its loss.
And now he and his family are sad and disappointed because I stopped using my married name a year after we married. I can't afford to change it legally, but on everything I use the name that makes me feel proud and happy. I can appreciate their hurt and how it must feel to receive emails from someone who refuses to use their son's name.
I wish I could find peace in using his name, but I can't, nor will I ever
