What should i do?

He was my friend and he liked me for 5 months. Every time he said that he likes me through his friend i said no because at that time i like someone else. Because he always stare at me and one day he said to my friends that he dream me every day and he wants to kiss me. the time passed by i just realized that i started to like him. I asked his friend to tell him that i like him and he gave me his phone number. On the last day of school i confess to him by text that i like him. And he said “ i dont want relationship. I liked you as a friend but what do u want us to be?” I said i dont know and he asked me to be friends with benefit and i said yes. We had sex and we kissed again before he left from my room after we had sex. After that he doesnt text me back. I text him again and i asked him “ are we done with friends with benefit? And what do u want from me” he said “ i dont know and i just want have sex” from that i never text him again because i asked him to come over to do it again and he always say he busy and cant come. Yesterday it was my first day of school. I saw him at school and his face like there is not something happened between us and i cant look at him face to face or eye contact. Im sacred. Now what should i do? I still have feeling for him and should i forget him or try to make him falling in love again with me? Hes not popular at school he doesnt speak english very well and also he just always with his cousin at school.
