Well, you have already blown it with this girl. You crossed into that friend zone which 99.8% of the time you will never move out of (unless of course you are in a movie
). Sounds like you need to do one of two things. Get over it and stay her friend, or get over it and stop talking to her. In either case, you will have to get over it. Painful to hear, but it seems as if you have wasted enough of your time pining over this girl so I had to get straight to the point here with you. It sounds as if this really never has been an equal friendship and that you most likely became friends with her because you were interested in her. Healthy friendships with the opposite sex don't develop this way, you started off wanting more then a friendship while she most likely wanted just a friendship and in a sense you have been lying to her this whole time. Do yourself a favor and break out of that mentality or you will be "the friend" to women all your life.
*Free Plan9 Tip of the Day* For the love of God, please don't tell anymore women (that you are not dating) that you jerk off to them each night.
