THE SECRET SCRIPTURE 5

In my book i have arrived to an important part because one of my main characters : ( Dr Grenes ) who is the doctor in our mental asylum. His relationship with his wife has been on a downwards spiral because they never had a child and that hurt Dr Grene's wife as being a lady and having maternal instincts that she could not fur fill. Soon she became elder and started becoming sick. Dr Grene and his wife barely spoke and one evening that changed they enjoyed their company together very much but after that amazing night. Dr Grene's wife died, we are now seeing how much this is effecting him and how he is changing his perspective on life and himself.. An example is that he shaved all his beard to feel younger. All theses different stories with narraters confuse me quite a bit but i am trying to understand.
