Attraction or Lonely?

Okay, so I've been with my boyfriend for 8 months now. And I love him to bits and pieces and he seems to be my whole world. We originally met in person but he does actually live a few states away and I'm not old enough to be able to move out as I'm only 16 and he doesn't have the money to move out yet. But recently at marching band (im on colour guard) I've started getting a little crush on a girl who's on guard with me. I have no intention or want to cheat so I'm not going to act on those feelings, or if i do I'd break up with my bf first, but I just dont know if im actually attracted to this girl or if i just want someone to touch and hold hands with and stuff. I know spending a lot of time with someone (i just got done spending 12 hours a day for 2 weeks with her) can sometimes cause attraction just because you're around them so much also. So I dont know if I'm actually crushing on her or if I'm just antsy to feel someone hold me again. I don't want to break up woth my boyfriend, but i just feel bad if i truly am crushing on this girl. Any suggestions on what I should or what Im feeling?
