Be up front, brutally honest with her saying something along the lines of; I initially was attracted but I am really glad we're friends because i realized at a certain point we shouldnt see eachother (quick transition) but that's not important. (if she asks about it play it as you normally would) i think you can help me better myself. Be up front and say something along the lines of i came to you because you seem in tune with a lot of weird things, something stating she's different, not in a good way but not in a bad way. You're clearly different too though, nobody has straight up wanted to reflect upon themselves, and now you're in tune with yourself and/or at least desire to better yourself (DHV?). Take it from there, maybe build up to asking if she was ever attracted to you, if she responds negatively say something along the lines of you were curious so you could find out if there was something that turned her off, smile big and do something funny. If she responds positively, you should know what you can do from there.

very unconventional obviously, meant for a certain type of girl clearly, just wanna hear some input, additions, suggestions.
