I need help. Im so lost?

hi guys. so Im so confussed right now. I need advice. So im a freshman in high school this year and at the begginging of the year, like in august, i fell in love for the first time. You know the person you see for the first time, and without saying a word to them you fall head over heels? thats what happened to me. Turns out this guy liked me too. I was so thrilled the day i found out. We started to go on dates and stuff, and in december we kissed for the first time. I felt so amazing and i felt like i was living a fairytale. He was my first everything. The first person who told me he loved me, the first kiss, the first person he i told i loved him......he was my everything. Well.....a few months ago we started acting like friends. Idk what happened, but it did. I started to feel like he was my big brother...u kno? well then i started to like another guy, and i asked him to sadie hawkins dance. He said yes, and at my friends house before the dance he started hitting on me (looking at me, putting his arm around me, etc.) anyways i loved that night and i was so happy. Well then i found out he had a gf. What a cheater:P so i got over him, but now i like someone else.... i know its crazy but its true. Hes really good looking and funny and sweet.....and i started to really like him. Well lately ive been missing my frist love at school. Hes always on my mind. I see him at school and i want to shove a sign in his face that says I LOVE YOU!!! im crazy about him, but idk if he likes me. I love him so much and i want him to feel the same way again. I want him to be mine like he was a few months ago. i still like the other guy but im in LOVE with this guy. It was love at first site. When we kissed in december i didnt see a spark..i saw a million fireworks. I feel like we are MADE for eachother. I love him with all my heart and i would do absolutly anything for him. PLease help me. Give me advice. How do i get him back? Who should i go after? HELP!
