My heart is broken and im in agony aaall the time without him. please help :(?

PLEASE READ - after a year and a half of flirting back and forth the guy i like brought flowers to school and asked me to be his girlfriend. i mean, i was sort of obsessed. i thought about him all the time. but i was careful not to be clingy and stuff but i think he knew how strongly i felt about him. anyway, after two months he broke up with me because he "lost interest" and then wanted to get back together the same day. i was paranoid all the time after that and i found it hard to be myself because i didnt want him to break up with me again. but about two monhs later, he did and made it very clear that he would not be changing his mind again. after all that time and him finally asking me out, it felt like i had won a battle or something. i felt victorious and i cant imagine being with anyone else and it seems impossible to love someone as much as i love him. still. i miss everything about him. we dont even speak anymore. i miss his eyes his smile his hair, his laugh. his... unique sense of humor, and how he always smelled like laundry detergant. and i know he doesnt miss me at all. i can tell. its been two months since we broke up and everyone says it will just take time, but i dont think ill ever be able to move on after everything that happened between us. whenever i see him with other people laughing and stuff, i get a twinge in my tummy because i just want to be a part of his life so badly. i want to know whats happening. i dont think this is normal but i cant help it :( i cant let myself get over it :( but i want to sooo badly.
