Bitchy MIL

My mother in law is constantly berating my SO and talking down on him. It drives me crazy and it hurts both of us every time she says something nasty about him.

Out of her 3 kids he's the only one who does anything for her. We live in his parents house, along with his two siblings, MIL doesn't clean, she barley washes dishes, she doesn't take out the trash or anything, except cook supper. Yet constantly complains about a dirty house and how no one helps her, yet, she sits on her ass all day watching Netflix.

Her daughter and other son, who are 23 and 17, don't do shit. They're the most disgusting people I've ever met, they don't do dishes, they leave rotting food in their rooms, they put their trash bags in the kitchen instead of taking it outside. They leave food to rot in the kitchen, in used pots, in the sink, on the table, on the counter, the refrigerator, and freezer. The daughter will put clothes to wash but then leave it in the washing machine for days at a time just for it to get all mildew stinky, rewash it and forget about it again. But MIL swears they're gods gifts to this earth and my SO is nothing but shit.

My SO is the only one who takes out the trash, I wash our dishes but refuse to wash other people's, I've cleaned the kitchen more times than I can count, swept, mopped, the whole 9 yards. My SO cleaned out their nasty fridge and pressure washed the grossness out of it.

We never get told thank you but it's not like we're really asking for it. We just want to live in a clean house. But MIL still acts like we're the dirtiest people here that don't do anything even though we're literally the only ones who do!

She even had the nerve to say that my SO would let her drown in the hurricane and not save her but the other two would come save her. Like that's just crazy mean right? Like bitch keep talking and we probably would let your mean ass drown!

I just can't take it anymore. She drives me crazy. As much as we'd love to move away from this toxic environment we just can't afford it right now. I'm scared this is going to cause a strain on our relationship because it just upsets me so much.

I guess I'm just looking to rant or get advice from people maybe in a similar situation.
