I think you have to man up and make it abundantly clear that you are interested in more. Get drunk with her and make a move. Don't worry if it makes you look stupid or like an a hole . Actually its a good thing if you become a bit of an a hole in her eyes. That's what guys are supposed to be. Its sad but true but girls are attracted to a bit of beligerence (don't go over the top with it though). Don't worry about the friendship. Obviously you are interested in more than a friendship. If it doesn't work romantically, and it ruins the friendship, go out and meet some new girls. This will also be a good thing as she might start to realize that she missed out. Do whatever you can to get out of the "friend zone". A hetero sexual male has no place being in that zone, it is the most futile place to be unless you actually have no romantic interest in a girl. And even if thats the case, don't be too much of a friend to her, or all her girl friends will think of you that way too.
