I've been friends with this girl for 5 years, and am only now starting to have feelings for her. I keep making connections to when we are younger that may prove I've always felt this way, but I'm unsure if it's all just in my head or not. I know it happens on tv all the time, but is it actually possibly to just start having feelings for someone you've known a long time? I'm not 100% on this girls sexuality, which makes me feel i may have been repressing these feelings, and makes it harder to know what exactly to do in this situation.
