It’s odd my new dp’s ex-wife has kept his last name even though they don’t have dc? Tbh, they were married about 7.5 years, together 14. They have been separated 3 years now and divorced since 2021, they don’t speak and it was her behaviour towards him which triggered the break up (I appreciate I only have one side of the story). It’s not a massive issue but I just think it’s a bit odd? I’d understand if they shared children but they don’t.
