W t f... help me before I go hurting someone!?

okay, so this guy, we have had an on-off thing since 7th grade and this year everything is just different. We werent ready to be together in 7th or 8th grade cuz we just werent but now it seemed like things were getting better and before the school year started, we went to the movies with mutual friends and we hadnt talked or even looked at each other since then. So at the movies he randumly layed on my lap and we made out a lot while our friends were just looking in disgusted lmao. So we have a class together now and he said that he at least wanted to work things out between us two and be friends and thats wat i thought it was FRIENDS! One day after school, we pulled me to the side and made out with me again and then he dry humped me .-. then ackward silence between us again and then we started talking again and the next time he wanted to "talk" he wanted me to suck his d**k, I said no cuz I was a good christian lmao and now he just moved on to another girl, who no oe likes honeslty and my friends told me that uring the whole on off thing again this year with him hes been all up on this other girl, cuddling her and crap. So, now we just aviod each other and having the same class and sharing a lot of teachers doesnt make that easy. I see him in the hall during every class change and its like why this year? but do you think he was just using me the entire time...? Note the new girl didnt come until after the year started but before he wanted to be friends all of a sudden.
