I in to not know what i feel for a guy?

Hii !
Last years in my class , there was this guy . In the beginning I didn't know him at all. Then during the year, we laughed together, there was this game of look between us. In maths class, he sat down next to me because I was alone , while usually he sat down next to his buddy. We used to look for each other constatly. We enjoied fighting. I started having feeling for him and every night I thought about him. I was really attached. Sometimes he asked me to make him cuddles. I don't know if we flirted but it seemed like. Then on a party he was completely drunk , he come see me and told to everybody that I was his girlfriend. He took my hand and put me a ring by saying that he married me. He asked me to kiss him and I kissed him on his cheeks but he moved his mouth to try to kiss me on the lips. But I stoped him because I knew his ex girlfriend and he was still in love of him. But I was really happy and excited. This guy was weird because I really don't know what he think about me. At the end of the yeart he spied on me when I spoke to a boy of our class. He believed that I was in love of my best friend ( its a guy) and each time he laughed at me. During the summer break, I didn't talk to him. Now he is in couple with his ex girl friend and we ignore us. And when I cross him in the corridor of the high school , he try to get my attention. So I don't what he feel about me. And I don't know too what I feel about him because I'm not jealous of his girlfriend, I'm rather happy for them. So if you can give me you opinion it would be kind , thanks! :) ( sorry for my English I'm a french girl !!)
