My wife of 35 years just became spiritual and now wants a divorce

How do I help my wife? Should I just let her go?

My wife and I were married 35 years ago. Just under 2 years married we had a near fatal car crash. We were both very injured, her permanently and on disability. She became addicted to opiods. After 31 years as an addict she quit and is now clean for almost 2 years. She did not seek medical advice, no meds, NOTHING! she just decided to quit and she did it COLD-TURKEY! She now wants a divorce. Most of our marriage she was an addict and I cared for her and mostly raised our 3 kids, now adults. We made some bad financial mistakes, lost our house and our savings. She believes in her "spirit-guides" through using dousing rods and believes everything "they" tell her. "They" told her that I have bad spirits/entities attached to me and they cannot be removed and they are only there to stop her in succeeding in her mission as "The chosen one" to help the world and change the world. Also she believes that I agreed to all of this in my "soul-contract" that I signed before I was born. She will not talk to a therapist or a psychiatrist, now or ever! She feels that there is nothing wrong with her. I love her and want to help her! How do you help someone who does not want help? It seems like a lost cause. Should I just let her go and wish her the best? Slowly starting to realize that there probably is no way to save our marriage. I DO NOT KNOW WHAT TO DO!
