Client question: "I have been dating 'my fiance' for over 2 months. He is in the process of divorce and I was so excited that he asked me to marry him. Now he tells me that he changed his mind and wants to break up. I can't handle this because I love him. What's wrong with him and how can I help him to change his mind?"
A more important question has to do with what is unsatisfactory about you. Your expectations are out of order and in need of repair. You are describing a man who is cheating on his wife and, yet, you believed that he would have been loyal to you. You were willing to accept his initial ideas.
It will be important for you to understand why your standards are so low. Therapy could help you to recognize who taught you that you deserve so little. Is it possible that you may be afraid to be alone? Counseling can also help you to understand that you have no control over his behavior. You only have control over your own reactions.
It appears that you have felt "loving" feelings for someone whom you wish existed. You can explore these concerns in therapy. This can assist you in gaining the insight you need to make better relationship choices in the future. Your current feeling is that you "can't handle this." Oh yes you can. What you cannot handle is your delusion that a cheating con artist is really a truth-teller.
