I think I am caving in. My husband requires more and more assistance which I try to give him in the most loving and caring way. His dementia must have entered a new phase. All of a sudden I get mocked and scoffed at and outright resistance when I ask him even the smallest favor, like to please sit straight on the toilet seat to avoid another disaster, or brush his teeth, which he insists he already did. I feel so frustrated and angry. I realize that his reasoning ability is gone and I must keep my calm, but how can I combat the resentment that is slowly building up in me.
