If a girl is bothering you, just be straight up, don't put her on a leash with mixed signals which is what it sounds like you're doing by keeping the "friend" window. We're complicated, when a guy says he wants to be friends, girls usually think it means eventually he wants to be more than that. So either stop talking to her completely or just give it a shot and date the poor girl. She said she's liked you for three years, thats pretty committed. If nothing is gained than a bad date, so what, least you tried. Give her credit for being honest, you on the other hand need to figure out what you want because it seems like you're stringing her along which is not cool.
If you're really serious about not liking her or wanting her then completely sever the connection strings. Easy as pie, if you find it hard to do that maybe you're missing your own feelings on something deeper.
Don't think it through so much, thats what girls are suppose to do, I would know. Take things for face-value, and figure out what you really want.
