why does everyone blame me for our relationship problems ands ay I am possessive abusive and controlling ?

fighting because she won't cook and she is eating subway in the bathroom with the dog and sleeping in a separate bedroom and she thinks she can come and go as she pleases I tried hiding the keys and keeping her in the bath room but she slid out the window of the trailer.

I have threatened to kill her as a joke which she did not think is funny and hover over her and follow her everywhere because it is funny to watch her freak out over a prank.

fighting because she wants to leave me but I hid the title to the car she uses she did pay for some of it and I do have another vehicle but I do not want to lose her this relationship is until death does us part.

Fighting because she wants to stay up and watch the impeachment trial and sit in a non approved chair after I have gone to bed and wake up at 10 30 because she works I don't want her watching the impeachment trial so I made myself stay up so I could check on her and kept turning it off telling her I could hear it even with cc and headphones on that almost turned physical because she was screaming at me to leave her alone. I pay for everything she will never make it without me. I hate when she works and it make it difficult for her to get there
