Dear Queenie,
My father was my mother’s first husband. She also has a daughter from her second marriage who thinks her father is the greatest guy in the world. Actually, he was not a very good husband or step-father. He would lose his temper a lot and he would ask me a lot of questions about if I was having sex with my boyfriend and want all the details.
He is dead now and my (half-)sister remembers him as being the world’s best father even though I and our mother have told her what kind of person he really was.
Queenie, how can we get her to see the truth about him?—Disgusted sister
Dear Sister,
It could be that your stepfather was a better father to his daughter than he was to you. Or, it could be that your (half-)sister is clinging to a fantasy about her father because she needs it for her emotional health.
Let her have her fantasy if it makes her feel better, and just refuse to talk to her about him.
