All true. After I learned of my (now) ex's infidelity, I discovered an old diary where she talked about her FIRST infidelity when we were dating. She was also insanely jealous of my friendships with other women, driving me to end a few of them. I also determined at least one of her closest friends was engaged in MULTIPLE affairs and feeding her "moral courage" about why their actions were "justified." This same friend also blocked me when I contacted her and wrote "You knew." She had no comeback.
