Is it normal that i'm in love with my student?

I had this student, he's a handsome young man who is gentle and very thoughtful. He used to stay after my class often to work on his school projects and homework and asked me for help a lot. I met him his freshman year and found out about his home life. He has a rough life since his parents are always gone leaving him alone with little to no money to go out of the country, so he usually goes without food. I ended up letting him come over to my house often for food and he stays to tell me about books he read that he thought I may find interesting. He bought a movie over that was based off of one of the books he let me read that I absolutely adored from his home country called Parineeta. It was a very romantic movie and after watching it he gave me a kiss. At first I thought about stopping him, but I somehow couldn't. I felt so weak and powerless like the strength just left my body. And suddenly he stopped and apologized for what he did. He stopped staying after in my class and I couldn't bring myself to talk to him or look at him in the eye. His sophomore year I found out in the teachers lounge that his father came back to tell him the news his mother died and he was leaving to Bangladesh leaving him in boarding school. He returned senior year and I saw that he was always late to school, skipping class, and some how always got into trouble. He was still the same kid but the last couple of years had changed him. Since he was often in detention and I was the one who had to take care of the detention class our relationship went back to what it had been. He was managing his school, work and ways to find contact with his dad and sister who disappeared from his life. I asked him to stay over at my house again since I felt sorry for him, and we became close again. One day I ended up letting him drink which I know was a very irresponsible thing for me to do. We both got drunk and had sex. He woke up the next morning and told me he was in love with me and always had been. And while he was away he only wanted to come back to see me. I told him it couldn't happen I was his teacher and I was older than him by 10 years. He kept it a secret since I could get fired for this. But after he left for graduation I never found anyone who was like him. No one thought as deeply as he did, or made me feel the way he did. And even though I told him to go away I still love him. I watched him grow for four years and I feel so close to him. I don't know what to do.
