I blocked my in laws from seeing pictures on Facebook

So I ended up blocking all of my in-laws from seeing any pictures on my Facebook, unless I want them to see it. I have been with my husband almost 10 years and none of them except for his 2nd cousin and mom and her bf have ever tried to hang out with me or get to know me. They have always been cold towards me and we have even not been invited to some of their family gatherings. So we decided that we didn’t like them anyways because they are all gossips and drama anyways and just stuck to small gatherings with my mil and her bf and sometimes the 2nd cousin, her husband and kids. As soon as I got pregnant my MIL changed towards me and would never ask how my pregnancy was, got upset about us having a gender reveal, wanted to know the name we picked instead of waiting until delivery like we planned, would never say I looked pretty EVER in any of the gender reveal pictures or maternity pictures, rushed to come to our house after our baby was born when we asked for no one to come until we were ready, and just made me feel like I was just an incubator. Before she left our house after seeing our baby she requested that I send her pictures every day of my baby. I have never had a close relationship with her where we ever texted or talked on the phone and at this point she made me feel so small and like she didn’t like or care about me that I decided not to do that. I would send her one here and there and then it started to feel transactional. Like if I didn’t send her a picture then she would be even more distant towards me. I also get TONS of baby clothes for free from a friend and I asked that she doesn’t buy any more clothes for my baby because I was drowning in clothes as it is. She never responded back to me and then I found out she told the clothing size to one of the aunts and the aunt had bought a bunch of clothes for our baby, so I asked that she wouldn’t buy clothes either. Everything just spiraled and my mil would leave comments like how great this picture of my husband and baby is and she would purposely not like pictures with me in it and I just started to feel uncomfortable posting any pictures of my daughter for fear of what my in laws would say. So I discovered I could limit who sees my posts and I made it so that the in laws couldn’t. Well today one of my husbands aunts finally accepted a friend request from last year on Facebook and was able to see all of my pictures since blocking everyone else from seeing them. I ended up deleting her and now I’m worried she’s going to spark up drama about how I blocked everyone from seeing the pictures and deleted her. It’s to the point where I want to remove ALL of them from my Facebook or delete Facebook all together. Does anyone have any advice or thoughts on this? I left a lot of information and back story out because this story is so long.
