Will he come back to me?

Sweetheart, just him saying he was sorry means that he does care for you. Most guys don't do that unless they care for a girl so much that they don't care about their pride. Sit down and talk to him somewhere quiet, and ask him if he wants to give it another shot, just one more try... I know that the school thing is hard, but if both of yall can make time for a party on the weekend I'm sure you two can find some time for you two, if you two decide to give it one more try. Best of luck and I hope things turn out for the best.
