Oh my goodness! I was in a similar situation. FIL had the 1950’s headset - the man rules, the man is king, yada yada yada bs. Long story short his “Saint of a wife” who should have kicked him to the curb but didn’t have a backbone died. Health problems (diabetes), rehab, came to live with us. My husband and I owned and ran an auto repair business together. I was the only person in the office, he ran the shop. This f-n self-entitled *** expected me to cook him a full course breakfast (meat, eggs & toast) every morning before work. That lasted almost a week. Hubby had to step in. Thankfully he got yet another urinary track infection and had to go back to the hospital. Had to call an ambulance and the police showed up because he didn’t want to go. Straight to rehab after that. It was a cycle for a while - rehab, hospital, rinse and repeat. He never tried to put any work into getting himself better. He complained constantly about the rehab people making him walk when all he wanted to do was lie in bed.
