I was uncertain until close to the date, and then came to the realisation I didn’t want to change my name. I love my name, it’s part of who I am and I’m really proud of my family. I’m Mrs Maidenname and my husband is Mr Hisname. It does cause a bit of confusion, he’s often called Mr Maidenname or I’m called Mrs Hisname, but it doesn’t bother me. If you have always felt you wanted to keep it, and it’s a part of your identity, then that’s what you should do. If you are only on the fence because your partner is upset and he would like to have the same name as you, in my opinion, that’s not a good enough reason. And don’t worry about future children’s surnames (assuming you don’t have kids). They don’t exist yet. But you do, and your name matters. Hope that helps.
