what to do when you HATE your in laws?

Chelsea
I will try to keep this short, but my mother in law and sister in law are like disgusting, horrible people. After we went through our second miscarriage they both were SO disrespectful. Telling us things like they are tired of hearing about these pregnancys that won't last.. we shouldn't tell them unless we know it's a real baby 🙄 ect ect.. not to mention they are both so manipulative and selfish and need the world to revolve around them and everything they say.. I am FED up and want nothing to do with either of them ever again, I also don't feel comfortable having my future children around them. (We are currently due in Dec, but aren't going to tell them, they get to find out when we announce it on Facebook) 
Is that wrong for me to not want anything to do with them?
How do you deal with in laws that you absolutely cannot stand? 
Ugh the struggle is so real 😭
