help me out please

My boyfriend has been through a lot in his life. He's sufferered verbal abuse from his mother and depression. When he was 17 he was admitted into a psychiatric ward in a hospital. He took medications and has been fine ever since. He said he knows how to deal with stuff now.. without the help of medications and that's been proven true. However, lately we've been arguing about a lot of things. Mainly, I want him to get his college application in before the deadline. He also says he needs to do his job at school, work at home, feels like he's not gonna make enough for car payments and stuff like that. Yet he is still shelling out 300 bucks to see me at college next month. Last night I was asking him about the essay again (which he started) and we got into an argument somehow. And he said all the sudden he felt nothing, he felt numb. There were no feelings insdie of him. i thought he was going to break up with me so I cried. It didn't even bother him that I cried because he usualyl will start to cry to. But instead he has no emotions and doesn't know what's wrong with him. He says he knows that he still loves me. Right now, he is just sleeping.He still says he feels nothing. He says its like everything in his body just shut down because he couldnt' handle it. He said he's not depressed because he doesn't feel sad. He just feels nothing. I don't understand or know what to do? What is up with him?
