Would you end it/take a break?

So it's my bf's 19th bday. Lately I've been down in the dumps due to stress with school, sports etc. I just snap at the littlest things because I'm so on edge. At the party I did my best to put on a happy face and enjoy myself. My bf could tell all day that something was bugging me. So after everyone left and it was just us, we went in his room to chat. He asked me a million times what was wrong and I just didn't want to tell him cuz  1) I didn't want to & 2) it would've hurt his feelings cuz it was about him. He got upset cuz I wouldn't tell him why I was upset and long story short, it ended with him saying "well you might as well get out"
