Brother in law and wife from hell

I just hate my husband’s brother and his wife. I honestly tried to like them for the longest time but i just can’t even pretend anymore. They’re self centered people who literally think the world revolves around them. They have a 2 month old baby and all they do now is complain about how hard it is to have a baby. They’re asking my husband and i to change his diapers and baby sit him while they go to the gym; they’re both on maternity/paternity leave for 1 year and they still cant handle it. My MIL is also taking care of the baby whenever they want. I’m 3 months pregnant now, and the only thing they said to me when they found out was “great now you can take our baby on playdates all the time”.

Yesterday we had a family dinner and my BIL told me to go change the baby’s diaper right in the middle of dinner!! Of course i refused and then he started laughing telling me that ill be a horrible mom. Whenever they’re around we are not allowed to talk about anything. They have to control the conversation and make it somehow about them or their baby. His wife is even worse because she is SO fake to my face and acts all the time yo impress my in laws, but keeps backstabbing me every chance she gets; whether talking badly about me to mutual friends or just bullying me (before i was pregnant she kept talking about my infertility issues to everyone and kept saying how she feels sorry for me, and i didnt even have issues). I wish there was a way to get them out of our lives forever; my husband has blind loyalty when it comes to family even though he acknowledges the pain they’re causing. We all live close by and my in laws keep emotionally blackmailing us to show up to every lunch/dinner/occasion. I really don’t know how i can get away from all of it, especially now that im pregnant, I cant handle the toxicity anymore.
