This reminds me of that incident on 2ch slightly, with that Densha Otoko or what's-his-name.
In any case, wish you the best of luck!
However, I think you need to take the lead more. For instance, to move your relationship forward, in a week or so, I don't know, but give it a bit of time, next time you are walking together, why not take her hand in yours? Or if it is winter wheresoever you happen to be, then that would be a good excuse to rub hands together, ro something, but slowly introduce playful, light contact into the relationship.
Also, you remind me in some regards of myself, however I'm still very withdrawn and have touble speaking to people. In any case, good job ^O^
