I'm so sorry she's being cold and hostile right now. The funk she's in may not have anything to do w/you. She'll work through this and be back to her self in a while. Let her fume for a while. If she texts you again, don't be so quick in responding to her.
You are absolutely right in stating that we can't speed up the process for them. They have to bake for quite some time before they are ready to come out of the MLC oven. Continue to work on letting go. If you notice, when you distance yourself from her, she tends to come nearer to you and when you start warming up and coming closer, she distances herself from you again.
Please take care of yourself. Try to find something fun to do this weekend.
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.
