When they are sick and don't want to stay with some guy anymore, they start talking to another guy, then slowly see if they have a chance and if the other guy will stay with her, when they are sure of it, they leave the first guy and stay with the second one. So they don't cheat and they don't sleep with the guy without leaving the first one. This did not happen to me, but I noticed that a woman was wanting to leave her husband to be with me, and I also saw another girl doing something similar with her boyfriend to be with a friend of mine.
