10% of extramarital affairs stay put but 75% of that 10% eventually split up. So in my female calculation 2,5% of all extramarital affairs survive.
rambling: I used to say that the feeling of guilt was useless. It's not. I feel that guilt tells us something. It tells your core that what you are doing is not OK. It warns you. It's there to guide you. If you keep ignoring warning signs eventually you will fall and break down. Being egocentric is the root of all evil.
