need advice

Ok so, my boyfriend is going through a rough time. He recently decided to go back to school. He is taking two classes and works 50 hours a week. He was having job problems (they all almost got fired), then he started to get behind in school, and his home life wasn't the greatest. When he is home he has to build a barn and a fence on his free time (so less time to study). The catch is if he makes less then a B then he gets kicked out. I've tried to offer alternatives for him but he wants to try on his own. But bc of all thisbhe is stressed and depressed and shut off his emotions and feels nothing but anger and was taking it out on me. He said he started to resent me and didn't want to, he was beating himself up more for doing it he said. Like a bad cycle. He says he cares for me and well he ended up breaking up with me. He says it's just temporary so he can focus on bettering himself for him and me. But he doesn't want me to shut myself off from anybody else in the mean time while he is bettering himself. I care for him and want to wait and be there for him but do y'all ladies think I should try or walk?
