Quick rant

So quick back story, my parents are divorced. My mother was never exactly affectionate and I was pretty much raised by my grandmother. Now that I'm pregnant, she was telling me to not shut her out like my mom did. My mom "shut her out" because she didn't let her take myself or my siblings out during the day to do her stuff. Here's where I'm getting pissed off: my grandma is super into church. She has a lot of friends and she told everybody that I'm pregnant within days. I wanted to wait to tell people since I was only 8 weeks at the time. One of her friends offered her, her restaurant for the baby shower. She calls me and tells me "I already have the place for your baby shower" and I'm like um, ok? Once I found out what place it was, I told her no. I'm not a fan of that restaurant. I was gonna ask her for her house since she has a huge yard for me to do the actual baby shower. She then tells me "we an do it at the restaurant" so I ask "how many baby showers are you planning on doing?" So part of my issue is that she wants to do a baby shower with her friends who I DONT EVEN KNOW because of she throws me a baby shower, they'll ask her why she didn't invite them. But I mean, who's pregnant, me or her? Should I decide who goes and what I want? Aside from that I wanna make sure everything's ok with it being my first baby and I'm honestly paranoid to mc, but fuck I'm just annoyed that she's making plans when I'm not even getting asked what I want. I understand she's excited but let me live my pregnancy how I want. She even made a comment about "what if your mom kicks me out of the room when you're giving birth?" Like homegirl, only my husband will be in that room when I'm giving birth. Once I'm done, y'all are welcome to visit but give me my fucking space
