that is so stressful even to an outsider. what do they fight about? the leader of the house has to give an intervention. or you and your wife have to move out asap.
I can feel your frustration, I'm sorry you're going through this. I think you can always communicate how this makes you feel and maybe setting boundaries might work too! Setting boundaries with your mom and wife to make them stop and explain to them why this isn't healthy and in order to continue, some changes need to be done. I hope that all of you get through this with the least damage possible
