To be fucked off with husband

[Crockof]

Aibu to be upset that my husband has just referred to his ex as My insert name ie My Sarah. We are married and have children just for background. He has no children with ex.

If he had said my 'ex' Sarah then it wouldn't have been an issue, right?

@Beach, I feel old, even though Phil Lynott's 'Sarah' is older than me now!

I refer to an ex as my when talking to one of my friends because he has the same name as her brother who I am friends with also. It’s just a clarification of which one I’m discussing If it isn’t contextually obvious.
