You're saying you love her? You're fifteen!

I'm sure you like her like alot though. No but really, don't wait too long buddy because while you're waiting, she could get scooped up by another guy who probably has similar thoughts to you, but he has a little more courage to act on it. That would really hurt if it got to that. Trust me.

What if you don't want a relationship, but she on the other hand, wishes a guy would ask her out. At least to go to a movie or a date. Something ya know? Do this, when you see her at school say hi and smile. Make sure she sees and hears you. Don't just hope that she looks your way, say something.

Small talk with her during the week. Things like how your teacher's a weirdo, or how the school work sucks, or blah blah. It shouldn't be too hard. Try not to get too nervous. She's a girl, but she's also still a person like anyone else.

Later in the week or next week when you're comfortable, tell her that you two should hang out for the weekend or something. Don't say, "I was wondering...if you're not doing anything this weekend...that maybe you'd want to..." Be assertive and tell her what she SHOULD do. It works better that way.

Be confident and go for it.
