I think about my history teacher a lot recently

Never told this to anyone, but recently, I jave to think back to this a lot. I need to get it off my chest. When I was 14, I was going through a lot. A friend of mine died back then, my parents weren't the best. My history teacher listened to me and helped me through it which resulted in me developing the biggest crush ever on him. Retrospectively, I think he liked me to. No way he had similar feelings for me, but now that I can look back on it, I think that he thought of me like a foster child or something similar. Nothing inappropriate ever happened of course, he always kept his distance and remained professional. Then when I graduated with 18, still having a crush on him, he congratulated me, told me he was proud of me for working through all the hardships and that he wishes me well. Then, we shared a hug. Like, that was everything my stupid heart and mind could have ever wished for back then. Years later, I saw him again, we chit-chatted and that was our last meeting. I think that is a good end for this odyssey.
