Still in Love

I’m in 10th grade. So I was with this guy about 5 months ago and he was just amazing. I’m the beginning, I thought things were moving to fast, so without any explanation I cut things off with him. I really hurt him by doing this. He trusted me and he told me he loved me and I New he was being genuine. I broke his trust and his heart and I still feel so bad. So I tried to salvage things between me and him and I ended up writing him two love letters. He told me that he was still unsure that he could trust me, and nothing professed from there. In those letters I told him I fell for him. Fast forward 5 months and I still love him. I see him around school and I remember how amazing his hugs were. He likes my posts on insta and I just cry at the thought of not having him. So I really want to get over him, but idk how. I see him everywhere and I don’t know how to move on. I haven’t been able to like anyone because I’m so hung up on him and nobody has showed any interest in me. Any suggestions?
