What am I doing wrong?!

Okay, so I really like one of my good guy friends, he’s actually the only guy I really LIKED, rather than just thinking a guy is hot, ya know? I’m a very outgoing-touchy person. (oh btw, he just ended a “thing” with one of my close girlfriends) He would come to me for adivce about how to “get” other girls, these girls being my friends I help him. I act like I’m super happy for him, but really it’s killing me! (not literally) Now that he is totally single, no hooking up, or things with other girl. I flirt with him 10x more than I usually did. I can’t tell if it’s working, if he likes me, or if he see’s me as a friend. We both make each other laugh, he told me I’m easy to talk to, I sometimes touch his arm or something when I talk (I do it naturally). We both jokingly make fun of each other, or mock something.. then laugh. I seriously can’t tell if he likes me, and I don’t know if I should tell him how I feel, or if I’m doing something wrong.. aah HELP. I really want to get him to like me as MORE than a close friend. I’m down for any advice. THANKS! :)
