I think I'm too late, and I really like this guy?

Last year this guy had a huge crush on me. He would text me every morning and say "Good morning beautiful:)" and I didn't really like it. Last year i was so into keeping my popularity status. I got popular in 8th grade (im know a freshman) and I wanted to keep it. I never wanted to stop the crushes from older guy and all the parties and attention I got. But then over the summer I realized I really wasn't happy with myself. I didn't like always having to count my carbs, straighten my hair and put buckets of makeup on. Even if I was getting attention from senior boys. So I stopped, and I realized who my real friend were. Now I'm really happy with myself and my flaws, and stopped counting my calories and ate like a real person. The thing is, the guy liked me before all that. And I kinda liked him, but I stopped when I got popular. But one night when we were talking and I was being a b*tch he said "I really miss you Paige. You've really become one of the girls we despised, I hope you sometime come back." and that got to me. But That was the last day of school, we didn't talk all summer. Now I'm back, I'm with my old friends and I don't do anything like that. Those girls dont even like me anymore because I wear sweatpants and I leave my curly hair. Anyways, he came in and I didn't realize how much I missed him until I saw him. He looked over at me and kinda smiled, like a proud smile, and looked away. Because I was so mean to him and thought I was better. Anyways, he didn't look at me all week like he used to. And yesterday I started to cry over it, I miss him and all the fun we had before I ruined my life. So I ran into his arms and hugged him and cried for what seemed like hours. But I still don't think anything will happen. How do I get him back?
