AIBU to not call FIL "Dad"

[HotWashCycle]

DP and I recently got married after years together. His elderly DF who is a widower has asked me if I would call him Dad in future, now that we are legally married. My own DF died when I was young, I was close to him, and miss him still, and I don't feel comfortable with calling anyone else Dad, even though FIL is a nice man who has always been kind to me. AIBU if I say I would prefer to go on calling him by his first name. Would appreciate views on this. Thanks.

YANBU, I find it so weird when people do this. My BILS all call my/their in laws Mum and Dad (even worse, the middle class ‘pet name’ version of Mum and Dad that my SILS use 🤢) and it just feels so odd to me, I physically couldn’t do it - I use their names when talking to them or ‘your mum’ etc. And it’s not like I don’t get on with them, I have a better relationship with them than my own mum! Just feels weirdly intimate.

That’s so bizarre of him.

It might well be! The title really caught my attention as it's something that happened way back in our family.

Agree

No - you still have a dad , albeit only on your heart now , just call fil by his name , I’m sure he won’t mind
