How do you deal with a 44 year-old daughter who verbally attacks her father (bad father, bad grandfather) and nothing we say seems to get through to her? Her mother (from a prior marriage) uses this daughter to air her grievances about her ex husband and the daughter seems to believe her. This has been going on for over 25 years. I am the second wife and have watched my husband (her father) age before my eyes every time she goes on the attack. He will soon be 75 and I feel he shouldn't have to put up with this for the rest of his life. What do we do?
