Mommas and step mommas!!! Lol

(I’m not sure if I’m in the right group for this but I just need some advice/opinion here)

I’m currently 6w pregnant and I recently got engaged to my fiancé back in may on our 1 year anniversary trip.

He has two babymommas/daughters. The oldest BM is super chill, very mature and respects us both.

The recent other BM (mom of the four year old) …. Some background story here before I go on lol

When she found out I was in the picture she took the daughter away for a whole year. She started saying how i was a just pussy and that my fiancé shouldn’t be taking care of my daughter or spending money on her since she is not his.

She Would send messages to my fiancé saying how she wasn’t over him etc etc.

A year later (now) when she found out we got engaged she now wants to let her daughter around but not have me involved in anything. She does not accept me.

My fiancé stands on my side and still includes me on calls/messages/etc because “you’re my soon to be wife” and we’re soon gonna have a baby. On top of that he does not want to speak to her bc he lost a whole year of his daughters life and more for taking his daughter away due to her feelings. So he hates her and won’t forgive her for the time lost but would still have to for the sake of the child.

She still asks/request for things to go her way.

I have not yet announced my pregnancy for so many reasons- one because I know the second we announce it- she will take his daughter away again. What should I do?

Also today we noticed that when he’s on the call with his daughter, the BM whispers in his daughters ear to ask where i am/doing.

The whispering part of her asking where I am/doing bothers me lol should I trip? Should I say something? I don’t wanna stress this man out more because it’s already a hard situation and I know he just wants to see his daughter.

I also know she’s a very immature person, bitter at that.

This entire time I’ve had let her shit talking and disrespect slide but now my patience is coming to an end LOL

Thank you in advance ❤️
