My sister has been disgusting to me lately. She is 20. We used to be great friends and she’s always been a kind, considerate person.
Last year she started an affair with a married man. She really thought he would leave his wife for her. Of course he didn’t. He got her pregnant and told her to have an abortion.
She did and then he cut her off completely. She used to send photos of his wife to me and her friends and call her an ugly old hag and so on. It was disgusting behaviour cos that woman did nothing to her.
I thought she learned from that but no she hasn’t. She is now currently sleeping with 3 different married men who are all 35+ and have kids. She thinks she is living her best life because they take her out on dates and buy her things.
I told her to get serious and realize the gravity of what she is doing. She doesn’t care. I know this is technically not my businesses as she is an adult but it’s just so cringing to watch, especially because I care about my sister a lot. What can I do?
