I understand having fleeting thoughts of this. However, when I really thought about it, there is no way I would want my FWH to feel the way I felt. I love him!
You can love someone and still realize the they need consequences for bad behavior, the consequences are for there own good, too.
Being branded a cheater is not a good label for someone.
It can harm one's career, business, can lead to false claims of rape or civil law suits, can cause death by an angry OW's husband, and can lead to the death of a wife, if the OW goes bonkers when dumped.
Also exposing oneself to deadly STDs that are more likely to be spread by engaging with a serial cheater is not healthy and can be deadly.
Why in the world would I want him to feel the crushing pain and devastation that I felt?
The same reason why you might briefly touch a child's hand against a hot radiator to show them WHY they need to avoid touching the HOT radiator?
If you have children then you know you can tell them until you are blue in the face not to touch the hot radiator, but until you show them how it feels, they will continue to hover closer and closer without a care or concern.
People learn best by example, Humans are not to far from chimps in that respect.
As Maya Angelou once said: Maya Angelou — 'I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.'
Beyond that an affair typically devastates the cheater's entire family. Their children, their spouses, their parents.
So, if their are no consequences for bad behavior what would be the motivation to stop?
Feeling the pain they caused their spouse, children and family is to my mind the consequence most likely to cause a cheating spouse to finally feel true remorse.
Lastly, its normal to hold some hatred for someone who betrayed you. You can both love them in some ways and still hate them.
There are many degrees of love, too.
Unless a person is co-dependent or has Stockholme syndrome, it is NORMAL to hold some hatred for someone who betrayed you, physically, sexually, and his entire family physically and financially.
