I am asking this for my sister. She is age 72, and her husband passed on a few years ago. Her husband was emotionally absent during most of their 40 year marriage, and she knew that he had an affair at one point. She went to counseling by herself, many times (he would not go), but she still is not at peace about his betrayal, in part because she can no longer communicate with him. Are there any books that you could recommend for her? She is not a reader of the Bible, but will listen to advice on a spiritual level. Thank you.
