In-laws

So I have horrible in-laws. I’ve had problems with my mother in law especially since my husband and I started dating. She has always had a jealousy towards my family. Always hated when my husband and I would do brunch with my family every Sunday for example when it wasn’t a tradition they had in there family. Like it was somehow my fault. If my husband wanted to have brunch with them he should have imitated. Mind you this is when we were dating when that drama started. Oh and She wore white to my wedding and didn’t smile in any pictures bc she said that my mom wore sparkles and she thought I had told her at one point no sparkles. She is Mexican so definitely a language barrier. And she adds and deletes pictures of us on FB and our son all the time depending on if she’s mad at us or not. They didn’t see us for 2 months when my son was 2.5 months old when we asked them to not come visit during the week bc I was going back to work and struggling with the little time I would have with my baby after work. I just didn’t want to share and wanted to get used to things first. In addition we asked them to please call before showing up unannounced bc she did that once when I was nursing and I just don’t like when people come over without asking or giving us a good enough heads up. Its just a respect thing to me. They ju wanted to teach us a lesson but what they don’t realize is that we have our son but they are missing out for a pointless lesson. She constantly calls my husband and talks crap about me and my family. My family has the kindest heart. What kind of mom does that? What is her goal to make us hate each other and divorce ? Horrible person if so. Anyways, so when this pandemic started they were not social distancing well and us and my family were. We literally didn’t go anywhere and barely do still, but they have been out and about with friends, going to restaurants, parties, etc. so we basically haven’t let them see our son since February. They are welcome to come from a distance but they said if they can’t come see him and hold him they won’t. And they basically stopped calling also for the most part. And they said that we are discriminating against them, and giving my family all the attention. My family is going above and beyond to stay safe and our son is first priority. We haven’t even let him play with other kids other than from 6 feet away. He’s 16 months with no touch interaction since he stopped going to daycare in March and I hate that for him so much. But we’re protecting our family. So what are we supposed to do?
