Cut ties for baby??

Long story short have this friend who uses me for money and what will benefit her. She never admits she’s wrong and will come up with excuses instead of saying she’s sorry. Since I got pregnant she’s been not helpful in anyway. Her and her family will say comments about how my mother is “a bad mom” (me and my mom had a bad relationship but getting on now and she’s supportive). She allowed her sister say I’ll be a better mother than mine which hurts. She will tell me I’m basically not able to care for my baby cause of my anxiety, she told me people will only become close cause I’m having a baby, and she is just not here for me when I need someone. I found out baby has fluid around their neck and it’s upsetting thinking it could have something wrong. I got the NIPT test so waiting for that is stressing me out. We’re fighting because I removed her cause I can’t be bothered with her and she is putting more stress onto me. I told her about baby and how it was upsetting me and I want someone to talk too and she said she’s too tired she’s going to go to sleep. She then said she’s going out and if she’s home she’ll want to talk our problems out before talking about baby problems. That upset me cause I would drop our problems for her and I have in the past. She was still mentioning I removed her and I basically said I don’t care no more, she’s a terrible friend because she doesn’t want to even know what’s going on and I don’t want her around the baby if she isn’t gonna bother. She replied saying I’m using my baby as pawn and people don’t ask about her brother and they were still allowed to see him and what I’m doing is childish. I said I don’t care because he isn’t my baby and it’s not my family if that’s the way you’s work then that’s okay. I upset her mom by saying that which i apologised for and it was 100% not my intention.

We went out and talked stuff out but I’m still not happy, I think our friendship is done. When I mentioned the comment about using the baby as pawn She said “she was angry”. She didn’t even say sorry which is all I want.

I feel like I’m not enjoying this pregnancy because of our arguing and I would be much better off without her not only over that but other stuff she did in the past. I’m trying not to have my baby in a negative environment and I want them to have a better life than me in a way.

How would I go about it ? I wanted to text her but knowing she would turn it into a fight. I feel as if my baby deserves better and so do I. This is my first pregnancy so if I’m over reacting please tell me. Thank you :)
