My husband has early onset of Alzheimer's. He has always had a one-track mind! He has always been a very difficult person and I've suffered verbal and sexual abuse. Psychologically, I've shut myself down on anything to do with sex, in order to 'live'. Now, all of a sudden he shows a lot of love to me, is crazy about me, but in bed, wants to touch me all night. I can't stand it but don't dare to react due to the verbal abuse I suffered. I also am lacking sleep. How do I handle this?
