What do I do with my love.

I am in love with this girl. But I am not the most confident person, and I am also somewhat a geek. Now also consider this. She has a boyfriend but I don’t think he us right for her, yet I have this deep love for her that won’t go away. Now lately me and her have become small friends but not extreme friends, and I’m worryed I might fall into the friend zone.now it is also one week untill school is out and I’m debating wether I should tell her how I feel. Can anyone help me.
