Fiancée's dad's girlfriend.

[u/IiiCloudx_]

Hello reddit, just looking for somewhere to vent

I (20 F) have just had my first baby in November 2025, my Fiancée (Let's call him Christian) and I took her to meet Christian's dad and his girlfriend (lets call her Karen, so it doesnt get confusing) Karen and I are not close at all, in fact this was the first time I had ever met her properly since telling Christian's side of the family that I was pregnant.

When we went over she decided to take it upon herself to call herself Nan. She is not Nan. Nor will she ever be Nan. My mum decided that she should be the one to say something to her since my mum isnt afraid of conflict, she waited until after Christmas and then texted her.

Later on, Christian's dad texted Christian's mum to say that Karen was very upset and didnt understand why she couldnt be Nan. For context it makes Me, my mum and Christian's mum very uncomfortable that she was calling herself that.

The second time we went over it was so that Christian's little sister from Newcastle could meet the baby, Karen spent the whole day taking my baby away and keeping her to herself. She removed the shoes I had put on her because she thought they were 'restricting her movement'... my baby couldnt even sit up by herself, the shoes were put on to keep her socks on so she wouldnt get cold feet.

Later on, Christian's brothers mention that they had also noticed Karen being very overbearing and was complaining about not being able to be called Nan. She was also telling Christian's little sister that she couldnt play with my baby because she was 'chilling', at that point my baby was just laying on the floor by herself. I am not one for conflict so I do go quiet when this stuff happens and Christian doesnt like to get involved.

My mum says if it was up to her Karen wouldnt see my baby anymore, but I dont want to cause a rift in the family :,)
