Fiancé referred to me by his ex's name

[GsdMother]

3 days ago and I'm still freaked out.
He was basically talking about how his mate had some medical problem and DP suggested that he give me a ring (nurse) and I said "yeah he could have done". DP then said "I said to him "just ring Angie" ..... Angie is his ex. They have been seperated 6 years and divorced 5. We have been together 4 years and are getting married in 10 days!!!! I tried not to make a fuss and just said "you told him to call who?" And he said "oops".

If they'd recently split and ours was a new relationship I could understand it but under the circumstances it's really freaked me out. I couldn't hide me feelings and said it had upset me, especially as he'd never done it before and we'd been together so long so he gave me a half hearted apology and said he was with her a long time and he made a mistake which I needed to get over!!

AIBU or is he? I'm now worried with our wedding fast approaching that he's actually thinking of her.

My dad has a category in his brain which is clearly for female members of his family with whom he has lived and with whom he has everyday domestic coversations. It contains my mother, my stepmother, my sister and me. He uses our names virtually interchangeably when having that sort of conversation. He also calls his granddaughters by each others' names, even though he knows quite well who each one is. He is just really bad at names. It annoyed my stepmother for years, quite understandably, until she realised that it really was pretty much meaningless.

Oh yes! Although the emphasis goes on my first two names and she some how injects dissapointment into my last. It's quite a skill.

My DP helpfully has the same name as my ex so I know at least I can never make that mistake!

Seriously though, I am sure it was a genuine slip up. I wouldn't worry about it.

I've done the same thing many times. I've also called my daughter by my ex husband's name, my brother by my son's name, etc.

I also once addressed my daughter as 'Mum'. I don't actually call my DM 'Mum', so not sure where that came from.

When I tried to introduce my current partner to my best friend I drew a blank on both their names.

I need a new brain.
