Ya know, your relationship sounds like my own relationship with my then best friend, now turned boyfriend (and still best friend). We had known each other for years, had crushes on and off, went out with others, but we did end up together as of two years ago. Your story sounds so much like my own...that I HAD to write. Ok. Now I will try to help answer your question. The thing that I would tell you to do is just be a friend. Be there for her when she needs someone to talk to, lean on, or whatever. Listen, love. It's ok. Be supportive of her relationship--as it seems you have been--I know that it is probly kinda tough to see her with this guy when you have fallen for her, but you are sophmores, and you never can tell what will happen later! (My boyfriend told me that my sophmore year is the year he really realized he liked me--and wanted to go out with me. At the time, I was in a relationship that I was very happy in, but he was just always there to listen and talk and just be a friend. After the relationship ended, he was still there...still wanted to be more than just friends, and I came to my senses and realized---the one was right here all along!) I can't say what exactly will happen with you and Katie, but above all, being there, being a friend is the best thing you can do. You never can tell what will happen in the future...
