mommy issues??? advice plz!!!

this is a long story but to put it in short, my mom and i didn’t have the best relationship growing up and i moved out right when i was 18 ( which says alot). 20 years old now and going onto 3 years with my fiancé.

Moved out with my now fiancé and last year she wanted me to say no when he proposed to me after i told her how excited i was about it.

Then now i’m pregnant with our first child and she called me a disappointment and is angry and said “ i know better”. i don’t understand what she means by that. To me it means absolutely nothing cause like what?

I don’t want her in my child’s life at all. We plan on moving closer to my MIL which has been so supportive since i met her like a mother figure to me. Is it the right decision to leave her out and not even invite her to my wedding?

She loves to bring a cloud of negativity over the most exciting events of my life. I love my fiancé and there’s nothing that’s going to change that. it seems like she wants me to run back to her saying we broke up or something.

What would you do in this situation cause i’m ready to never look back. My child will have amazing grandmas on my fiancé’s side of the family.
