Mother-in-law want to pick my baby name what should I do😕

Hi girls so my mother-in-law is crazy with the idea that she's having a granddaughter she's a mom of 4 boys looking for a girl 🙈 and when I was pregnant and give birth to my son she wasn't excited at all and I didn't feel she love my son (not calling him, ect) and since I meet her she's trying to get my life miserable so when she found out I was pregnant now with a girl she all crazy texting me asking how the belly but never ask for my son I try not to disrespect her and just say OK but lately she's texting me telling me name for the baby name that I don't really like at all and I don't know how to tell her that I don't like it 😕😕 I hated to say no to people even if the hurt my feelings b4 I hated to be like that 😢 sometimes I just want to be badass with people but I can't....what can I do???
