I don’t know what to do...

So this is gonna be a long story, sorry. I’m currently a freshman in high school and I met this guy in 6th grade. At first I didn’t like him but we soon became best friends. Over the years I ended up growing feelings for him and apparently he did too. We dated in 8th grade and he was the first guy I had ever fallen in love with. We ended up breaking up because of a misunderstanding between two of our friends but we stayed best friends and choose not to get back together because it was a really rough of both of us. He told me that if we get back together it had to be naturally. Not him asking me out or me asking him out which I agreed with. Recently I’ve come to terms that things most likely aren’t gonna ever happen between us again but the other day I texted him asking him if he wanted to to hangout. He said he was busy so he couldn’t but later in the night just said “meet me at the school in ten?” (our old middle school is right next to our houses). We met up and ended up just talking for an hour even though it was dark and he could only be there for twenty minutes. Right as soon as we started to leave I looked up and noticed you could see the stars. My two favourite things to do are watch sunsets and watch the stars so I started watching them. He came over and said he couldn’t see them. We both wear glasses and he rarely wears his but I almost always wear mine. So I have him my glasses and we have the same prescription so we just passed them back and forth. We sat there for at least 30 minutes but I started to get cold. I get cold very easily because I’m extremely skinny. I started to complain and he said we need to move around to keep warm. So we started walking a little bit and then he turn to me and asked me if he could carry me. I said yes so he picked me up bridal style and started running around with me in his arms. Only reason he stopped was because my leg accidentally hit a metal pole and he thought he had hurt me (which he didn’t). Then we watched the stars for a few more minutes and walked home because it was super late. Ever since that night I don’t know how to feel. He makes me so happy and he such a nice guy. My parents absolutely love him and have always wanted us together. My mom even made a rule that in middle school I wasn’t allowed to date anyone unless it was him. Only problem is I don’t know if I should really try to move on from him or see if we end up anywhere. It’s been four years of me liking him and not really trying to pursue anything with other people. I’ve liked other people but I’ve never felt the same with them as I do with him. All of my friends at I should move on and my brain says I should but my heart says I can’t. I honestly have tried to move on from him with this girl I meet awhile back but it kinda felt like I was cheating even though we aren’t together. Also yes I know I’m young but he’s really special to me and has stayed by my side through my hardest times when most of my friends just abandon me. Any advice?
