That is so true for my parents, my mother especially. Playing the victim card is essentially playing to someone’s guilt. The number of times she exclaimed: it must me horrible to be my daughter! Of course my sisters or I would immediately give in on whatever the argument was, and assure her she was a wonderful mother. Toxic people like narcissists and sociopath use emotional blackmail and manipulation to control their targets.
Especially when a little girl comes In between a love that wasn't hers. Convincing him to leave behind what he truly loved because he "isn't married." She will learn one day how awful it feels to have someone come between the love she has for someone. Maybe just maybe she will realize what she did in her past, grow up and hopefully feel bad for all the damage she caused.
