Could this be Karma

Good day house, I used to be a mistress to a married man, I have never been married and I think that karma is messing with me big time by having infidelity happening in my own family. My parents have married for about 25 years and my dad recently confessed to my mom about having an affair he had 2 years ago. They were having some problems beginning this year, about him using a commenting on this woman's photo things like "you are so beautiful" etc on Facebook. He claimed it was all casual, non serious and just socializing for the fun of it. He deleted the app but somehow we managed to find out that he took it underground and was texting the woman with actual phone numbers (as opposed to using the app). It broke my mom's heart. They moved past that as my dad vehemently denied anything serious going on and was mostly home accompanying my mom, bringing her out for lunch and basically being very loving towards here. I do trust him on this somehow. However, recently, my mom went to a pastor that sees vision and the guy was able to tell her very exact and accurate details about her life that she never told anyone before). So after talking about her life and kids, he guessed her number of kids + gender perfectly etc Anyway, he then proceeded to tell her that her husband HAD 3 affairs before. She was surprised. She went home, confronted him, and he confirmed the affair from 2 years ago. The lady is 20 years younger than him and near his workplace and got her number and basically was contacting her everyday. Somehow I just don't feel right I don't want my mom to stay with a cheater but at the same time it's my father. I'm repelled and sad all at the same time. Perhaps it's really karma for me to be involved with a married man before and now this is happening to my mom. I don't know if I should advise her anything or just pretend that all's okay.
