To all of you saying, 'tell the wife', have you ever been the 'recipient' of betrayal?
You see, there is a HUGE disconnect between intention and result. The person doing the betraying 'doesn't mean' to cause this much harm. S/he is thinking very very selfishly, only about their feelgood moment, an affair (being admired, desired) raises their self-esteem hugely. A large part of the problem is that they are not thinking of their spouse. In fact, they are not thinking at all. How many times have people heard 'I didn't mean to hurt you'?
The knowledge of an affair is absolutely shattering, in ways I can hardly describe. You self-esteem is gone. You feel ugly, unwanted, unsexual. You are so traumatised you don't even know what is real. I used to wish the world came with one of those packing boxes 'this way up' with an arrow. It makes you doubt EVERYTHING. Once your innocence is gone, it is gone. This is the one area where I think pure applied honesty is not applicable, really.
Please, please don't visit this holocaust onto the one blameless person. When someone is being selfish and thoughtless, they are in a little bubble of fantasy where they are in control. The issue here (the disconnect) is the fantasy. So an outside person, bringing a bit of reality of DISAPPROVAL and SHAME (and a bit of disgust) - could jolt the selfish arse into getting real about what they are doing and what is really important - and to turn away from his path of destruction.
The betrayers have no idea how destructive they are being, and what they are destroying. The disconnect (intention and result) is soooo toxic I think they should be challenged and given the option to stop and the wife given a chance to keep her innocence. It is ENORMOUS hard work to get to the place where 'his behaviour does not define my worth/I am not defined by him'. It has taken me 3 years and I and my children have lost so much.
If they are too addicted and choose not to, well - hell will be visited on them anyway. I would not wish this pain on my worst enemy.
