Our thoughts are with you my man. As Jim Morrison said, "This is the worst part of the trip." Give her a lot of space. Unfortunately, she came back from the trip angry, not your issue.
The more you pull, the more she will push away from you.
Ignore her. Reject her. Make it obvious that your life will be fine without her.
When my W and I first separated, if I went dark for 24 hours, she would automatically call. You could set your watch to it.
