BF Probs

So I've had this bf for 4 years and the past year we've been on and off.. I've had another partner since our split but can't seem to move on from him. I want him back but he cheated on me several times. He expects me to ditch my friends and not talk to anyone, no party's, no friends. I want him... It's my senior year In high school too. So any advice? Does the Pain ever go away? Will I move on? Should I?
