Son hates me.

I am in my 60's, retired. I no longer need physical care and feeling good. I am able to walk, think clearly, cook my own meals, bathe etc. My middle-aged son cared for me and took complete control but I don't need him now. I should have died 2 yrs ago and through his innuendo's I believe he was waiting for me too. my income is not enough to live elsewhere and we both own home so feel stuck and he won't leave cause house paid off and free rent. we aren't talking to each other due to ridiculous arguments that don't make sense. I actually feel psychologically bullied. Anytime I want to do something he blocks me ie, after discussing and getting his approval I bought tent gazebo to sit in backyard but he the last 3 months he kept giving excuses...first the ground not level so I had rototilled, then too many rocks and glass which there wasn't but had it picked up, then fence need repaired for dogs so family member offered but he refused saying only he can repair but had to work (plus he sprained foot) so offered it as temporary fix and free but he refused, then he no cause he couldn't pick up dogs poop everyday so I bought me pooper scooper and we argued, then I started putting up with family when he was out of town but his wife called him and he called family and said put on cement slab but he knows too small and gazebo frail and need stakes in ground to stabilize and dogs would knock over so family left, then he said I would have to wait for a cement slab....we never eat as a family, interact, he rewashes my dishes when they're clean, doesn't want me using refrig cause my food will poison his even if bagged and sealed, won't put in a/c unit but has one in his bedroom, hides TOILET brush (can't figure why), can't have visitors or he gets mad so I feel isolated, had towed my car not out of concern for my safety but he has 4 vehicles and doesn't want me taking space, he pointedly gives me the silent treatment, he stopped me from cooking stating the filters will burn, oven heat makes him hot and microwave takes electricity (I snuck in a coffee maker in my room and the warmer hot enough I can steam veggies and wraps in foil to eat hot food)...you get the picture. he held a grudge against his grandmother til she died over a misunderstanding that she tried to resolve so I think he is doing the same with me. he did not grow up in an abusive home but his wife did and has convinced him he did too. it may be what bonds them. so I don't know how to make my life better. no one is listening to me and son mad if i speak out so I've stopped.
