What if the person has been married to the grouch for over 38yrs? then what?

I was in love with husband when I married him. but over the last however many years he keeps changing, more demanding, throwing little boy temper tantrums, and demanding and pouts something ugly if I say NO or I am not interested. He for whatever reason feels entitled because I no longer have an income because of health problems of mine. When I was pulling in a 6-figure income everything was different. I had a say-so kind of and then he got hurt in an accident, and never once did I make him feel bad or like it was his fault he had become an extra burden on the household with our teen aged kids at the time. That was some years back and now I am the one who need busting up emotionally and physically. Now everything seems to be my fault and he is a stingy penny pincher with me, and I feel like a small child because I have to 'ask' for household money, because he loves to make me feel less than and that must make him feel 'more than'. Divorce would be the only way out but how would I pay my bills with no income. I am like so many females. I am stuck in a loveless marriage where I feel used and used up by this man. I am feeling like a creep because I feel this way. I wish I had the answer, and i would be outta here yesterday. He is a 'i am right' "she is wrong mentality" and he loves it that I have to 'ask' and beg for grocery money...but he eats here too. he lives here too. these are house bills. I dont get my hair done, my nails done, nothing for myself except pet food for the dogs. he hates my 2 dogs just because. I wish I could leave. i wish it was better. I just want this to go away. and he has changed since we got married. anything I might suggest to him to make our love life better...he chooses to ignore. He is what I would call the *30 second man*...cause that is how long it takes for him to shoot. then he leaves me in his heel dust getting back to the TV in the front room. not a word from him either---No-- I love you, No holding or tender moments before during or after. NOPe Nada...nuttin......... and he wonders why i am not interested. menopause...because I need a pause from this man....should have called it man-opause....thanks for reading if you made it this far. done now.
