Alimony

I have been married for 6 1/2 years and my husband keeps saying he wants a divorce because I can’t work. I have been disabled from birth ,and officially considered 100% by social security administration at the age of 12 and my husband knew this before we ever got married. He was fully aware that I’m not going to get any better as my condition stem from a birth defect(spinal bifida). Why my husband is using that as an excuse for a divorce,I’ll never know, I believe it’s because he just doesn’t want to take care of me anymore,as they cut off my disability check and my medical a year after our marriage because of his income,so I’ve been totally dependent on my husband for all support. If we end up divorcing after 6 1/2 years,would I be entitled to alimony or any spousal support,and if so,can you give an estimate of how much and for how long. He makes $30.00 an hour as a millwright and has an average of $80,000.00 taxable income. His hours do vary but he is guaranteed at least 40 a week with pay,wether working or not,but when working usually work 6,12hr shifts a week with overtime,time and a half on Saturday,and when working sundays makes double time,so his lowest check a week is 853.00 bring home,after taxes and his highest is $3360.00 before taxes,our insurance is around 60.00 a week and his retirement savings takes out 11 or 12% I do believe,other than that it’s just taxes. He gives me 100.00 a week in my bank account,which he opened and is a co account with him as well,and occasionally gives me a little extra or pays on my main present medical bills but mostly pays his own bills off to get them off his credit. I don’t like asking for anymore money,even if I need it because he gripes at me and says my 100 is for my gas n cigarettes or whatever I need but he doesn’t realize or just doesn’t care,100 a week doesn’t go very far,especially when I have to travel an hour and a half on a regular basis to my doctors offices,and monthly out of state to the doctor. I also have many other medical conditions,some that have just came about over the last 2 years,however very serious and life threatening and are irreversible such as heart failure and chirrosis of the liver. I just feel like he wants to get rid of me because of my medical conditions and the cost of my medical necessities and keeping insurance on me through his job. I would really like to know if he does divorce me,will I be entitled to any kind of payment from him and a guesstimate of any, I am afraid of being left without a way of living and surviving since I have no income of my own now and haven’t since October 2015
