The cold behavior you're seeing from her is not uncommon. You're locked in a game of "distancer chicken" and she doesn't want to be the one to crack first. When you stop pursuing her, and stop sharing intimate information with her, that makes her uncomfortable. She likes it much more if you're "on the shelf" waiting for her should she decide to return -- it's an insurance policy.
You do need to take that policy away. That's not to say that you're not interested in reconciling -- you are, but the point is you're not just going to wait around until she decides she's interested, you're going to live your life and take what comes.
When you pull back, she will pull back more. This is a ploy to get you to pursue her again. She wants to make you uncomfortable enough to come running back professing your love and telling her that you miss her, etc. It's a self-esteem boost for her and a return of the comfortable insurance policy. Don't do it. Eventually one of two things will happen -- either she'll make an overture to you (or start pursuing you), or she won't.
