This dream shows that you still have her place in your heart, which is her punishment for abandoning you. You blame her for our separation, hoping that she will admit her mistake. You think she is unhappy because you think it is her loss to leave you, or a speculation about her present situation.
I don't know the real situation of you two, but as far as this dream is concerned, you are a person who can easily blame others for your mistakes, and expect the person who has offended you to have a bad life.
In this regard, in your later life, you should always reflect on yourself and check your mistakes first. Only in this way will the road be smooth and your heart be peaceful.
