Mother in law

For the most part my mil and I have gotten along. I would noticed she would say things that would bother me a little but didn’t pay attention to her. Everything changed when I got pregnant. Shes came to visit my husband and i once since I’ve been pregnant. She says rude things now that really bother me but never in-front of my husband or she sends me rude text messages. Ive told my husband about her message and he says to ignore her and don’t reply, but even when i don’t reply she texts me again saying something to really get me mad. Like even when I ignore her she’s pressing my buttons. I really think im nice to her and don’t understand why she changed with me. On Monday we found out that we are having a little girl and i send her the picture of our ultrasound and the text i got back was “her nose is so long”. I don’t want her to continue to me like this because she’s literally pushing me and my baby away. I’ve tried to talk to her and she blamed everything on my pregnancy. Even if I wasn’t pregnant the things she says aren’t okay. I feel like she will always play the victim and just cry if my husband tries to talk to her. She also tries to copy certain things that i have or do. Makeup house decor clothing and even my hair color! Idk if she’s jealous that im pregnant or if she feels like her son is going to change because we are going to have our own family and things are going change. We haven’t told her that we named our daughter Ximena Alise. My husband picked the first name and i picked alise because of my mother Alicia. My husband loves my mom and they get along. He literally thinks shes the best mil that anyone can ask for. He loved both names and we decided on that. I feel like once she finds out shes going to tell me something and not my husband. She also said she wanted to be in the delivery room and i said no because i don’t feel comfortable with her while im giving birth to my baby girl. I told her it’s different because im not her daughter. Of course she got upset but i cant be okay with that. Like i said i just don’t want her to continue to me this way because she’s pushing me away and i want my baby to be around because that’s her grandma but I can’t be treated like this. I need advice...
