1. Do you still love her? 2. Do you like the person she is right now? 3. Is the door still open and you feel that you can reconcile w/her at some point? 4. Have you forgiven her for her behavior and will you be able to accept her for who she is right now?
Here's what I would do...if you are still interested in reconciling w/her at some point...follow her lead. Allow her to pursue you for a change. She's the one that wents a little nuts, so she's the one that has to prove to you that she is trustworthy and when back your trust and respect for her. Don't pursue her right now. I think she's testing her toe in the pond, but still isn't ready to give her all to the relationship.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
