Three idiots!!!

I really need to vent! I have two sisters in law and a mother in law. My both sil and mil don’t treat me with respect and mil always support her daughters and always worry about them. I think she should be focusing on me being her daughter in law. She goes and talk behind my back to her daughters and tell them everything that goes on in between me and my husband, in return both sil’s would conspire against me to my mil and my husband. Luckily my husband loves me and my daughter a lot and it don’t effect him whether I talk to his sister or not which is good but my mil won’t stop sharing our private life with her daughters and she don’t share anything that goes in her daughters life so it’s frustrating! I have confronted her twice about this and she always say oh I never share anything about our house to them and about them to you and I’m like this ain’t possible. I just don’t have any proof cz my sil don’t speak to me at all cz I’ve told them off for stop interfering in my hubbys and my life.. I just don’t know how to spend life with this type of mil under one roof!!!!!!
