Mil drama with baby shower

Hello every my mother in law and sister in law planned our bridal shower I asked them to include my family and they didn’t I’m now 26 weeks pregnant and my sisters are planning and put an invitation out to DH mother and sister and they haven’t contacted my sisters about the shower and my mil came to me and ask for an update on shower so she can help plan so I gave her the update and she started to change everything we wanted and I told my DH that he needed to talk to his mom and took him two weeks and when he did she didn’t say anything and everything I said she had a snotty response and attitude. what should I do? They are very religious and don’t want to be the bad one to the rest of the family.
