I hope things go better for you. My heart hurts when I read your story. If you are going to stick it out, maybe you can take comfort in the fact that after you both die, the thing that she could not conquer in this life will be taken from her and you will have your wife back. That is not very comforting in this life but you can always rely on our Savior when you are feeling alone. He felt all our pains and he knows what you are feeling. Take care.
