I feel you. My parents are the same way. I got a similar sort of situation. Truly miserable and hate each other. Been threatening to divorce each other for years, since I was a child but never have. Because they’re miserable they take it out on everyone else, which isn’t right. It sucks your in that sort of situation and I hope you can move out soon then or find someone else you can stay with. It’s not fair to you to be in this sort of situation. You deserve better.
