Confused with boys? Does he like me or not or does he like her?

I started liking this guy in my homeroom around november. finally i got the nerve to to talk to him and we started being friends. he asked for my number because he was going away for a little and wanted to text me during it, i was really excited and thought that he may like me. a lot of my friends thought he liked me too. and a lot of the time he acted like it. example- doing a pinkie promise in the movies and holding it for like 15 mins or so. so we texted and everything was going good then i had a get together with my friends and they stole my phone and got his #. and now he texts my one friend all the time and never texts me. ( the friends he is texting is my best friend and is she's really really pretty, prettier than me). but sometimes he still texts me and it seems like an excuse to talk to me if you know what i mean (like he used to before when we texted) but not as much as he texts her. he talks to me in person more though than her at school. he's kind of shy though so yeah. i've been so confused and really sick of not knowing. also how should i deal with my best friend. you would think she wouldn't answer when he texts because she knew i liked him but she does anyways. and she knows he's not texting me. i know it sounds bad how i am saying it but it really hurts me and i think she knows he may like her. i wouldn't do something like that to her, although i would now, and plan on doing so in the future if such situation presents itself. :D also she used to call him weird when i texted him, she doesn't now that she texts him, what's up with that? i can't really talk to any of my friends about it because it could lead to a mess that i don't want. i just need to know what's going on. also, it will probably help me move on, which i am actually progressing on. it's just seeing them and watching my best friends phone go off with a text from him while mine stays silent hurts a lot. Thanks bunches. i am 15 if it helps.
