Well i was in similar position (as usual LOL) me and this girl where good friends, infact she often called me her best friend. Then we got closer and eventualy i asked her out by which time she had decided she was not going to let herself fall for me because she dint think she stood a chance. Anyways she went out with someone else for a few weeks and eventualy realised that it was me she loved all along, so she told me and now we are together. But dont expect her to come to you, let her do the rounds a bit but stay as close as you can and be there for her. They like that, make her laugh now and again aswell and if she doesnt fall for you then she is a fool.
