Maybe she is going to return the favor as your "gift"
Seriously though, In the other thread there was some good advice. I've told a woman before that I was friends with that I had feelings for and she said it wasn't like that for her. It may have been awkward but I tried to just do it without much though and we are still good friends because she values me as a person. This girl sounds like she values you alot. The every detail thing is exactly what I would get from my friend.
I think it's just a confidence issue you are having. The fact of the matter is, women love confidence period. Even if you aren't confident, you should be projecting it at 99% of the time. Be cocky, but not an ass. Just go for it. BTW, I did kiss her and she kissed me back.
