It has been 8 years since we brought MIL to live with us. She never cared for me since I married her son, but was OK until last year. She is taking her anger about living out on me now, so my husband has taken over majority of her care. We got a new person three weeks ago to come out and shower her but she started lying to the caregiver saying that I am hitting her and the caregiver is acting strange. My husband told the person that his mother was lying, but the caregiver is acting cold to me. What should we do?
