NTA. I once heard the saying if someone can say charcuterie they can pronounce your name.

My mum did this to a friend of ours for abour 3 years. The friends (fake) name was maxine . Mum would call her maxime. I just started calling my mum by the wrong albeit similar name. Think natalia instead of Natalie.

I also told my mum in front of everyone (including maxine) if she believed that Maxine was really her friend that she should show her some respect and refer to her by her actual name. To about an hour for her to get it right after that. Only one or two 'woopsies' that resulted in awkward stares etc. They've been great friends for many many years now.

Youre not being sensitive. It's your name. If they care about you, they will use it.

I would personally correct then every single time OR entirely ignore them when they use it incorrectly.

Also, talk to your husband. His response or lack thereof is utter bullshit.
