Advice on my decision

Hey everyone,

I’m seeking for an advice if I’m doing the right thing of having the thought having my husband’s family not meet my baby. I’m 4 and half months pregnant and i have 2 children with my husband and we are happily married for 9 years already. Recently October of last year, his family and I are not a good terms. One of his sister’s wants nothing to do with me, doesn’t like me or i should believe she never did. She stated that she would never step a foot at my house or never come to any of other gatherings including my kids birthdays. Because supposedly i disrespected her which i believe I didn’t. My husband and i threw a small birthday party for my son on Oct. His family has no boundaries at all and seem that always have the right of everything, I had maintained quite for a long time whenever I’ll see something isn’t right or i just don’t agree on something especially when it has to do with my kids or my husband. My husband never had the courage to say something to them when he doesn’t like something so this time I decided to speak up and that’s where everything went downhill with his family and i feel in part with my husband because he constantly tells me I should’ve never said anything. At my son’s birthday, his family decided to open his birthday gifts without even asking if it was ok. New toys were all over the place, other kids starting to use them and lost several pieces and they didn’t even bother to stay for the magician that we hired, after opening gifts they left, without saying goodbye or a thank you, nothing. My husband got upset but didn’t say anything. I was furious but i let it go that day, but next day I told my husband to let them know what they did wasn’t acceptable and should let us know if they can do that. But no he said he was going to let it go as usual, so I was already tired of their disrespecting decisions from the past and i sent them a respectful text message starting about thanking them for coming over and for the gifts and i stated that next time I would like for them to let me know if they need to leave earlier and want my kids to open their present that they got them to let us know next time. It took them 2 days to reply until one of my husbands sister reply to a long paragraph saying I’m such a childish, ignorant b**** why couldn’t i let stuff go especially now that the oldest sister was having medical issues and their mom wasn’t in the mood of having any drama and she’ll never step a foot at my house ever again. (To mention she reply the message tagging my husband at the convo). My husband never replied but the private message that she was sending him saying that she feels that she needs to beat my a** and he had to calm me down, after I was trying to defend myself with her insults. After that, the sister block me on FB and the other 2 sisters just deleted me even my husbands mom. So apparently they all got offended for saying something. My daughters birthday came up on January at my house. Ofc i didn’t want to but i didn’t wanted to make it about me. My husband invited his 3 sisters , mom and dad. And guess what? None of them showed up for my daughters birthday Beacuse “I supposedly offended them” that being said them and i stopped talking, i get pregnant, and i told my husband i wasn’t going to tolerate any negativity especially now I’m pregnant. We did a gender reveal and with my pain in my heart I told my husband i didn’t want them there. We planning a baby shower down in the road and i also don’t want to see them or be around with negativity flooding in the air. Also I been thinking and here is where i need an I advise. I haven’t spoke with my husband because i don’t know how to tell him. I don’t want them to meet my newborn baby. They’ll meet him threw social media and that’s how far they going to go. Why? Because it loud and clear that since if they want nothing to do with me, why should let my kids be around them if they had never had the interest to look for them. NEVER! they been invited for kids sports activities or school and never showed up. Holidays like Easter and Xmas if they had bought them gifts they always wanted us to go to them and have my kids get it. So if they don’t have interest in my kids why should I have them meet my newborn if I know it’s going to happen the same thing. Am i being selfish? Am i doing the right thing? If so, how should I approach my husband about my thought?
