Why is she obsessed with her name and title?
I'm a Dr Maiden Name and when at work sign and refer to myself as such.
In other situations I sometimes get called Mrs Maiden name or Mrs husbands name and I don't really mind unless it's relevant such as signing papers etc.
Titles say nothing about who you are. They refer to a role you take on. She rejected the role but feels the title still reflects something about her.
It's like me retiring and insisting everyone still calls me Dr Wasp. It may be correct, and I can do it, but unless I'm working as a Dr is it necessary or important to keep correcting everyone?
Those pair are the biggest egotists imaginable and they think their titles say something about them.
In reality the fact they still use them and talk about them says everything.
They really are numpties.
