AITA?

So when I was 7 months pregnant my husband and I were living at his grandparents house where his mother also lived. They were helping us out financially so we could save for the baby - as this is our first - and save for a living space because they were planning on selling the house and moving across the country. My MIL has always financially depended on other people to make her bills or to buy groceries. When my husband and I first got together she was always asking him for money monthly, to pay all the phone bills in the house, groceries etc on-top of the rent he was already paying at the time. She even had him buy new washer and dryers for the house and then send her 1400 dollars to fly his brother in and get him a birthday gift. We found out that his brother didn’t end up getting a gift from his mother and just the flight was bought. So my husband told her to keep that money and pay the phones for the year. Skip to when I first found out I was pregnant she was super excited but she was with an alcoholic/abusive guy who we had to press charges against. I told my husband that in no way will he be going around our child, he agreed. So we made our boundaries very clear that when the baby comes she is only welcome to come visit the baby but he will not be. This started causing problems, she would make snide comments and his grandma and mom started treating the both of us differently. We would go and visit my husbands dads side of the family, they’re good people - supportive, stable and welcoming to everyone. His mom always had an issue with them, making comments about how it made her sick we would visit his other family. My husband starting feeling bad for even going to see them so we wouldn’t tell the family when we would go. Later in the pregnancy we were deciding on the name for the baby, we wanted to hyphenate the last name between his current and his dads last name (I was told when he was born his mom decided to put her last name down instead of his fathers) husband liked that idea. So we kept it to ourselves for a little bit and we’re going to tell the family when we wanted too and felt ready. On easter weekend we kept getting called from his brother, as his mom found out my husbands step mom was co planning a baby shower with my mother. It seemed like Husbands mom was annoyed and angry that this was happening as she was planning her own. We both thought it would be the best since she doesn’t like husbands dad side of the family and they like to cause drama about them. My mom also wanted to be apart of a shower and husbands mom wasn’t involving her in any of the planning and previously offered financial support. So we explained this to him and in hopes would calm his mother down. Now, my husband and I decided to hook up a family album app, so we can share the photos of baby with everyone as we don’t want photos posted of her on social media. On the app I had written her name with the hyphenated last name and this completely slipped my partners mind when he invited his mother to join the app. We got another phone call that day and she was absolutely livid. When we got back to the house his brother was raving about if we hyphenated the last name I’m going to look like a W***e and people won’t see our daughter as my husbands because she has two last names. Then everyone started talking to him and trying to convince him not to hyphenate the last name. So I stepped in and ask if they thought maybe I should be part of this conversation since I am the babies mother and have a say in what I name her. They ignore me and continue to talk down to my husband as he’s tried to defuse the situation. His grandfather asks him “what gave you such an idea to do that” so again I stepped in saying I had suggested it. They all huffed and signed but continued to only talk to my husband. So I started to get irritated, I told them that they can have opinions but what we decide in the end will be what we name our child and that they don’t have any say on what we name her. So they all turn to me and start yelling about how I’m a C**t and basically told me I’m no longer welcome and to gtfo… at the time of this argument I’m 7months pregnant and super hormonal. His mother comes out and starts giving it to me as well, telling me I need to leave and if I don’t she’s going to call the police. A who bunch of profanity was thrown at me. My husband was completely baffled, he didn’t know what to do expect he called his dads side of the family and they let us stay with them for a few weeks after this incident. After this all happened, my husbands mom, his grandma and grandpa and brother all don’t talk to him and have cut him off and told him to stop trying to involve them in the babies life because he said that they needed to apologize to me but they don’t think they did anything wrong. Should I feel guilty that they won’t talk to him, my husband says he feels free not being around them and he doesn’t have anxiety but its also the family that he’s known all his life. So he could just be saying this? Sorry for the long story, I could have added more but thought it would be a doozy
