We made out but he has a gf he hardly talks to and he says he likes me but is still datin her!! HELP?

ok so me and my friend Chris are good friends and we talk the whole time every day in latin. a few weeks ago i started to have a crush on him and then on superbowl sunday we were flirting a lot and then he kissed me and we made out. PROBLEM. he has a gf!! he barely talks to her and says i am prettier but he wont break uup with her. he says he is in a tough decision process. today my friend helped me realize he is just playing me so after crying a little and moaning around my friend called him and told him i was sobbing my eyeballs out!! and then he texted me and chelsea took my phone and told him to F off and that im pissed at him when i just wanna be with him(: im so cunfused, and idk what im going to do tomorrow in latin. Right now chelsea is at church trying to make him feel bad i guess. oh and he also thinks i now hate him and he says he still cares about me and never played me. HELLLPPP!!
