Idk what to do 🥲

So long story short my fiancé and mom don’t really get along and my mom has some multiple things to me about me not him and now my fiancé is saying he doesn’t want anything to do with my family and she cannot help me with our daughter anymore. My fiancé is going through some things and hasn’t really been present or helping me with our 5 month old and my mom has been. I really need help tomorrow but he is telling me he does not want her help. My mom has apologized for the things she said to me and I just let it go bc I know how my mom is. Anyways he wants me to ask his parents for help but they wouldn’t help me like my mom does. Do I just straight up tell him she’s going to my moms bc I need help before I have a break down? Or am I wrong for still wanting my moms help? Idk what to do
