There's this girl that I love a lot but she has a boyfriend already. She's one of my best friends and she is also my prom date. I don't think that she has any idea that I have feelings for her so I plan on telling her at prom. Is that a good idea? Her boyfriend is also one of my friends and I don't really want him to get mad at me so what do I do? How do I tell this girl that I've had feelings for her for a while now??
