My SIL really regretted taking her husband’s name. She always said in her country women don’t do it. Then she got divorced and she got sort of talked into keeping her married name, because she had young children and lived in the US. I told her to keep her married name and so did her lawyer, maybe other people did too. Then, she married another man years later, when the kids were at the end of their high school career. I thought for sure she would go back to her maiden name. Nope, the second husband really cared about her taking his name, so she did. She was not thrilled about it.
At one point I told her I regretted not supporting her when she was divorcing the first husband. I told her I knew how much she wanted her name, her birth surname, and she said she no, that it was better she had kept the name her children had, and her kids who were at the table when we were talking about immediately said it would have been awful if she had changed her name back when they got divorced.
Mind you, in her country, when you marry, you drop your mom’s surname, keep your dad’s surname, and then add “de husband’s surname.” So, Ana Perez Jimenez becomes Ana Perez de Estrada. Now, when Ana writes her full married name everyone knows she is married, because the de signifies she is married. But, a lot of people don’t bother writing the whole thing out. When I write my name, no one knows it is my husband’s name, except to say I don’t really “look” like my married surname.
