I need to vent.... MIL issues 😠😠😠😠😠

We moved in with my in laws because they were sttuggling financially, BIG MISTAKE!!!! My MIL thinks shes always right about everything and is super jeleous when shes not included. She loves being the center of attention. Well lately my husband and I have been detaching ourselves from his parents because theyre constantly arguing and fighting about the dumbest crap!!! Im due in a few weeks and we are looking for a new place to stay. She criticizes my cooking, my cleaning, everything I do. We always buy groceries, we try to make sure to stock what they like too but they always get into my pregnancy food. What really threw me over the edge was today when she bought food for everyone but decided to bring 1 cheeseburger for my husband, my son, and myself.. im so mad!!!!!!!!
