Yes, it is her stubborness and her feelins of hopelessness. But, she deep down knows what she really wants. You just keep showing her that it is not too late. She may feel like she has to continue the path she is on to justify it. Help her see how life with you is as great as it gets, you are not the same man, and when she comes back you will be there to work on it together not blame her for her stupidity.
