once you get over the bare desperation of being single and stop looking, a girl will come up...also, try to be friends with girls first, without expecting anything more to happen.
Better to just come straight out and tell her tbh, theres nothing to lose. If she laughs and ridicules you for it, you dont want her anyway.
Also, IMO being a friend first isnt really a good idea, since if you ask her if she wants to be your GF, you risk the whole "I think of you as more of a friend.", argument.
