Is it normal to have these feelings...

soooo basically, I spent all of my sophomore year pining after this really shy guy who has never even kissed a girl before. we spent all year texting each other and telling each other our likes, dislikes, interests, etc. I l know more about him then some of his best friends probably do. anyway, over spring break we finally hooked up, and then a month later, he told me he didn't really like me, and, worst of all, was leading me on because he felt sorry for me and didn't know how to tell me he wasn't interested. my friends all tell me he just used me to finally make out with a girl, but I can't believe he's the kind of guy who would do something like that. anyway, it's the end of our junior year, we haven't spoken a word to each other since then, and I am still head over heels for him. the worst part is, he sits right in front of me in my english class. I'd probably be over him by now if I didn't have to see him every day in class! what's worse is that I have a boyfriend who I care about deeply, but I've still got feelings for this guy, too! is it normal to STILL be attracted to him? after all, we only hooked up once! my friends all tell me to get over it already, but I just can't! am I an obsessed freak? or is this normal?
