I love my boyfriend and i wanna help him. But i cant. What can i do?

My boyfriend and i have been through the goods and the bads. Unfortunately, he's been having a bad month, his car broke down 4 times in a row, his parents are giving him too much stress, and college is even more stressful. He says that the only reason that he has now to wake up in the morning is me. Even though he says that, i really really wanna help him out more but i dont know any other way that isn't helpin him out with cash(which he wont accept) for his bills and stuff to help with relieving the stress. I really feel useless having to see him so frustrated and sad. Any suggestions? :(
