Monster in law baby shower ?

I don't want to come off as ungrateful at all because it isn't the case. So my husband was texting his dad last night told him my mother in law is throwing me a shower not asking me ... keep in mind she has made 0 effort to really talk much to me and when she has she's been well a little bit rude and nutty . Knows none of my friends or family and didn't even introduce herself at the wedding .. soo i mean who's coming ? Lol her friends ? Family? People i don't know or even worse people i dont like and she knows it ? . My friends found his family very rude at the wedding and would rather have their own thing for me . I'm also not one for girly all eyes on me type stuff. I mean is it weird she just told me she is having a baby shower ? I haven't had one before. What do i do ! Lol i have anxiety just thinking about it and who she will invite and what it will look like .
