My mother is 96 and thinks my 90 yr old father is having an affair. She had made up all these stories about how this woman calls my father and spend the night with him. Mom lives with me because she had had several falls and I've been her caregiver. My parents home is a two story with the bathroom upstairs and the it would be expensive for them to have the house remodeled. Plus, my dad wouldn't be able to care for her. Mom talks of nothing else but this affair. She cries all day, won't eat more than one meal, and gets so agitated at night that she can't sleep. She asks for dad to come over and says she misses him, then when he's here soon she does is make ugly accusations and verbally abused him. Yesterday he came by because he misses her and again but she kept up the verbal abuse and she all evening she cried and begged me to call dad and tell him to come back. When the paid caregiver is here, mom will call dad 7 to 10 times. Dad won't answer the phone because it's upsetting for him. We worry about his mental health as well. I can't reason with her and she thinks I'm against her. She's on Quetiapine and Lorazepam. Last night she refused to take her medication until my son finally convinced her. Then she started coughing and choking. Not sure if those pills went down. Respite for me? That's a joke... I still come back and don't know what to do.
