Dramatic, overthinking, or being reasonable?

To try & sum up everything in a shorter paragraph…

My MIL and I have had a rocky start from the beginning. After 2 1/2 years of my husband and I being together and I got pregnant, we mended things & things got better. Throughout time, things have just been off and on. Well the other day she asked us over for dinner. My husband told her we already had plans that night and we had to do baby shower stuff. That night on Facebook she posted this thing about how a mother will always love her son more than a partner. She also shared a post that said something like “sometimes you just want to make someone a pie” and it was the lady from the movie The Help. That morning (morning of my baby shower) she shared a thing about loving her daughter in law & only tagged her one daughter in law and left me out. Fast forward to the shower, we were running behind getting everything set up. I was helping my mom cut sandwiches and then my group of work girls started talking to me. Across the building she yells “Hi ____!! Just wanted to let you know I’m here” then when she was leaving she said “bye see you tomorrow morning… oh wait…” meaning she would see us at church but we don’t ever really go so she was being a smart ass about it because she disagrees. So later my husband calls her and asks what’s up and if there’s a problem between her and me. She plays victim and said she just feels awkward around me & my family & my mom never talks to her. Yet she doesn’t talk to my mom either. My mom is super introverted. She told my husband that she feels like I just have never truly accepted her. My MIL and step MIL as weird as it is are BFFs. My step mother in law didn’t even talk to me at my own shower. She avoided me when I was over by my FIL talking to him. When leaving she ONLY told me bye because I was literally right by the door and she pretty much had to. I saw her last night at a visitation and we made eye contact and she looked away from me real quick. I just don’t get it. Neither one of them come and see my kids now and they don’t have like any memories with them. But they treat the other grandkids differently. They definitely favorite the other ones.

Being 7 months pregnant and preparing for our last baby, the selfish side of me doesn’t want either at the hospital. But I know it’s still my husbands family. He literally said that his mom bullies and is kind of mean to the girls that aren’t blood in his family. But then says that’s am just how she is. How is that okay to deal with just because “that’s how she is” ?? I feel like they should respect me as a daughter in law and mom of her grandkids. I don’t even want them holding my daughter because they are rude to me & don’t care to see my other kids so why act like they care to see my newborn baby girl?

What do you guys think?
