My husband is in poor health. He used the Book of Changes to tell fortune, saying that we were contradictory and divorced me.

In this case, I suggest you communicate with your husband well and tell him not to be superstitious. I believe that as long as you two don't give up, your health will get better. If your husband still insists on divorcing you, it can only be said that he doesn't love you enough and would rather believe in superstition than your feelings for so many years.
