I absolutely agree with this. She should get a divorce scary as that change might be to her. Could it be the fact that she is married holding her back from moving in with you? Maybe on some level she feels a moral tie to stay in her marriage. However, she needs to cut that tie first I'm sorry to say. If she does want to spend the rest of her life with you she should be willing to take that step.

Change is hard I know. I struggle with it too. But in this case it is necessary for her to move on from her marriage.
