Do i still have feelings for him?

i go to high school wit my ex. He has a girlfriend that is bi. When me and him used to talk, she would always walk with him and like it would make me mad. So now that he goes out with her I always look for him and he always lookin for me. in the beginnin he would walk with her everyday & walk her to cl. Then when i went to his house & told him i cant stand when they walkin & kissin, he stopped walkin her to cl. he doesn't even acknowledge her presense at all. He finds me & walks with me. While she somewhere else in the school. But anywayss. I get mad when i see them together & i give him dirty looks. i ignore him when he with her. i get in a bad mood for the rest of the day if i even see them together. i wanna kno if i still have feelings for him. i still love him i kno. When i see him i get nervous & start fixin myself. lol. When he talks to me i jus stare at him smilin. I still answer his calls. I still talk to him period. While on the other hand, my ex ignores his ex girlfriend completely. He even put a restrainin order on her. Idk i dont wanna hurt anybody. But the worst thing is that my ex even lives 2-3 minutes away from me. We used to ride the same bus. But i drive now. But after school, he'll call me & ask me if i can come over to his house. Sometimes i do sometimes i say i have to work but i really dont have to work. He comes & see me at my job on the weekend when he drivin around the area. So can someone please help me. idkkk who i love more. im in love wit my boyfriend. he so perfect he dont are who around he jus grabs me & kisses me. but wit my ex when we was in school we barely held hands. we kissed when the bell rings & everybody goes to cl. sometimes we barely didnt even kiss. But i didnt want anybody to kno we tlked. cuhs then girls woud try to get at him. But i need somebody to help me. pleasee
