Sagittarius with a qs about virgo female

Hi
I am a sag born 20th of desember. I have been talking with a virgo female on MSN and my attitude has always been to almost never initiate conversation, she mostly did that. I also never hinted anything to her about wanting to meet her or anything, because I liked too much just talking with her. Then one day she asked me when we were going to meet up, and I said soon.
Then I did something stupid and sent her a lame e-mail, but an honest one, where I told her about my biggest weakness, and she said after that that she was disappointed that I thought this weakness would be something she would get stuck up about, because she wasnt this kind of person. But after that we started talking on the phone, and we were going to meet up, and she said she wanted to meet me and so on, I even went to say hello to her sister, and she told me how her sister more than approved of me.
And even after telling her how important it is for me that she is straight faced with me, I now suddenly get a cold shoulder from her. So I do not know what is on her mind, but seeing that she was the one who took the initiative on MSN and to us meeting up, and now she is cold, I have come to the conclusion that if this is going to progress anywhere the sag has to take the initiative and brake through, because I dont think she will ever be able to make up her mind or even speak her mind now that she obviously has doubts.

My dilemma is this:
Should I just let it all go and if she wants to say anything to me then she will.

Or should I ask her to be straight faced and tell me exactly where we stand so I can get off the hook?

Or thirdly should I just keep contact with her and be a friend and try to set up a meeting some other time? I lean towards this.

Any help and comment you can give me to try and understand her is helpful.

thanks for advice,
Mads
