Why am I so obsessed with this one guy?

i hear you girl!! This sounds ALOT like me. okay, you might not like my answer, but oh well. I would say tell him the truth. it sounds like you really like this guy and he might like you back. Don't let an opportunity like this go by. i liked this guy that liked me back and I didn't tell him how i felt and i ended up losing him and going through more pain than was necessary. He might not like you and it might be really awkward, but at least you know you tried and he knows how you feel.
