Long, advice needed please!

So we recently had some family drama between myself and my husband with my brother. It’s a long story I won’t even share details but simply my grandpa recently had some problems and had to move out of his house into an assisted living home with my daughters birthday right in the middle. I kept asking for updates about him and if my ma was going to make it to her birthday and I guess it started shit with my bro. So my bro called us out talking shit saying if she makes it she makes it but she doesn’t need to be around idiots for a birthday party in the middle of what’s going on with her dad and calls my husband a few names. So my prego hormones have been really good this time, I’m handling it better and not nearly as crazy as I was with my first but every once in a while they get me emotional. So his message hurt and my husband was on his way home from work, it’s the middle of the night so I cried and my husband read the message and just rampages back at my bro. So that made shit worse and he ruined his relationship with my ma from things he had said. But when it came down to it, it was all still about me. My daughters party comes and my ma comes out and she brings my sisters husband (they live in another state btw) my daughter was so happy since she loves this new uncle lol come to find out while although he did come because of our daughter, it was planned he come out to ‘protect’ my ma from me. So that I don’t try to get her to stay the weekend I guess?? So I spent the night of my daughters party upset and crying after hearing this. Thinking he was protecting her from my husband starting shit but no. All week I had hardly spoke to her and didn’t say anything at the party trying to make her stay so like.. why?? I had already accepted that she was only coming the day of her party so I stopped mentioning it. So she’s still stressed about my grandpa getting moved so I haven’t said anything to her about what we found out. So I’m wondering for advice about what to say to her when this stuff with my grandpa is over with. It’s frustrating since I’m due in less than 2 months and my husband is basically done with my family after all that’s happened. Like I’m upset about all this but I still want her but my husband doesn’t even want her around our new baby now. What do I do?? My sis and bro live far away and we lost our dad over a year ago so my ma is all I have left. But I’m just shook that they felt like she needed to be ‘protected’ from me, it’s hurtful. Especially when it’s my own mother. I feel like the black sheep. Thank you for reading
