SOS HELP! BOYFRIEND TROUBLES!

okay so lately me and my boyfriend have been fighting non stop and he is just super sensitive all the sudden to everything and I can't stand it and I'm sick of feeling bad for "hurting him" even though I didn't do anything like he makes me feel bad for hanging with friends and I'm done and honestly want to break up with him but help! I have 2 classes with him and I feel like i can't break up with him or I won't be able to go to those classes! What do I do?!!! I am in highschool and I just want to live and have fun and I'm sick of him acting this way and constantly controlling me and I just wanna be on my own
