Do you have any kids? I was keen to change my name back so that I had no association with my ex, but a friend pointed out ,that then the kids would have a different name to hers/mine. She simply said “why should I have a different name, I still want my kids to be “associated” with me, and feel “part of me”. Kinda made sense so I am waiting until they are older! It won’t make any difference when they are married!
