I would be happy to help assist you in understanding your dream. Your dream is normal in the current situation you are in. Having lost your husband, your dreams are going to be processing the impact it has made on your life. It will take some time, as you will continue to dream of your husband for a long period of time. Since he was leaving you for another man, can be showing the emotions you are working through. Perhaps you have feelings of why he was taken from you. If you have anymore questions please feel free to ask. My blessings to you on your path of healing.
