No. People cheat all the time and want to continue their marriages. Some people want their spouse and their lover at the same time. Some people want to fix their marriages after cheating. Some desperately want to be forgiven for cheating, but their spouse can never get over it, and leaves them eventually, leaving the spouse that cheated with a long life of guilt.
I believe a lot of this is true, but I think if the M is strong then there wouldn't be any infidelity. It is only when one spouse feels unhappy or unappreciated that adultery can happen.
I am sure there are a lot of couples who have survived infidelity, but I wonder how many of those were just "one-night stands" compared to an actual EA and PA? Seems to me that it takes a lot for an individual to carry on an A of any kind. They have to live a double life. They have to become someone who lies to so many people that trust and love them. They have to live with the constant fear of getting caught. Therefore, IMO, they would have to be completely done with the M in order to become this person because of the fact that their M's would most likely be over anyway once it was discovered. Not too many people would take back a cheating spouse.
