I have liked this girl for about 4 years. We have been best friends from the first time we met. We hang out with eachother all day. She doesn't have any other friends except for me. Last week, she told me she likes this guy, and I don't want her to know I love her, so I told her to ask him out. She didn't... Yet... But I'm scared that she eventually asks him out. I wanted to ask her to prom next year, but... Do I tell her and risk ending our friendship? What do I do?
