Mother is Boycotting My Baby Shower

So I'm not sure if this is where I should post this, but I just needed to write this out because no one in my life seems to get it.

So I'm 23 going on 24 weeks pregnant with twins. I was preparing to have my baby shower I about a month and a half since twins usually deliver early. My friend planning it needed a list of people from my side of the family to invite. Now I'm not completely sure who I should invite because I haven't been around my extended family all that much growing but I'd love for them to be there. So I go to my mother telling her I need her help. She's always telling me, "you have a mother you know" for everything because she doesn't like my mother-in-law helping with anything since I'm not her actual daughter (idk why my mother is like that smh). So instead of helping me like you think she would, she goes off saying it's "tacky and hood" that I'm involved in my baby shower and that I should just hold off. What!? Hold off for what?? She sure wasn't gonna have one for me. She made that clear saying, "who said anything about having a surprise shower for you?? You're not the type to do those kinds of nice things for".

I go to my sister to vent about it (wrong choice) and she basically tells me my mother doesn't want me to have one until after the babies are born because people will think the babies were conceived out of wedlock.......................😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐😐 FIRST OF ALL, nobody even knows when I got married because she made me have just family at a very small and private ceremony. And EVEN IF people assumed they were conceived out of wedlock, how is having the babies first gonna change anything in anyone's mind?? It won't. SECOND OF ALL, I don't care what people assume about me at all! My life and babies are none of their business or concern! I honestly believe my mother is upset because I don't want her to plan it. She wouldn't involve my husbands family, she wouldn't even include my friends, she'd make it all about herself. I can't take this 😭 I feel so sad all the time about this and I should be happy and enjoying my pregnancy 😞 I don't think I'll end up getting to have a baby shower. My aunt told me she'd help me make a list of people to invite, but knowing my mother, once she gets wind of that, she'll just tell everyone not to come and not even come herself. She's really selfish that way. I'm just so sad and I don't know what to do 😞😞😞
