Why should I put up with this man's careless attitude?

Im dating this guy who thinks that hes got the whole world figured out....Im homeless right now and so is he, he gets social security and I work to get my income, its not much, but I need to keep this job. He doesnt like it because I get such little pay as a cashier, but Ive explained to him that its not my lifetime career that I was doing to get back to college and finish my degree, he told That I dont need it and to put my plans aside. Another thing is he seems to have an attitude about my appearance. Okay, Im doing what I can to stay healthy and be a clean person even though I am homeless, I see customers all day, and even though I work part time I feel that my health and hygiene take precendence, and it helps me to keep up the pace. When I told him this he told me, theres the door, because he doesnt like me being proud and being stubborn. It doesnt matter either when I try to work with him on ii. I am taking one day at a time to get out of being homeless.
