Don't be surprised if when you back off, she contacts you more. They like to do things on their terms and in their own time, even if it doesn't make any sense to you.
I tried backing off the past few weeks and only talk to her when she contacts me first. It seems to be just the opposite to what you said though. She contacts me less as more time goes by. She seems to be detaching more the more I detach. Her birthday is next week and I really want to call her and ask her if I can take her to dinner. I don't know if I should though or not. I got up enough courage last night to call. When I talked to her she was busy so she said that she couldn't talk, so I didn't get a chance to ask her. I'm afraid that she'll say no. I know that I need time and patience, but they are so hard to give when it feels like it's all slipping away.
