It goes beyond "Why?" in my opinion, for me the more important question is "How?"
In our situation the answer to "Why?" has been:
1)He had been living on another continent for 2.5 years for work reasons, coming home every 6 mths for 6 weeks - this caused 2 issues, one being that he was treated like a super-hero by me and the kids every time he came home, he got used to that; secondly, he got used to living the single life, free of the daily grind of nagging wife, whining kids, housework etc. The A happened 6 months after he came home permanently - he was miserable being a full-time husband and dad, he wanted the care-free single life he had become used to and he was no longer treated like a super-hero because he was behaving like an irritable, miserable jerk. He was filled with resentment and feeling sorry for himself.
2) The OW treated him like he was some kind of god - she agreed with everything he said, she told him he was clever/gorgeous/funny/sexy....you name it, he was it personified. She lavished attention on him the entire time he was at work. He loooooooved the ego-stroke.
3)Conflict avoidance. He is a MASTER avoider of conflict, he will ignore issues and bury the resentment deep within, rather than having it out with someone.
4)Poor coping mechanisms - he had not the first clue how to cope with his negative feelings
5) She was available and he wanted her. Simple as that really.
Now for the important bit: How? How did he allow himself to do what he did? How did he think it was okay to have an A? How could he live with himself while he was behaving like that? How could he throw away all the years of marriage?
The answer to that is that:
1) He was selfish, had always been selfish, he felt entitled.
2)He had piss-poor boundaries. He acknowledges he was way down the slippery slope before he even realised it. He flirted, she flirted, he spent loooots of time alone with her at work (smoke breaks, lunches etc)
3)Compartmentalisation. I totally don't get this concept but it is a reality for MANY WSs. My fWH could put OW and his relationship with her in a box and when he was with me he would seal up that box and it was as though it didn't exist. No guilt, no shame, just life as usual. (WTF?! Like I said, I don't get it)
4) Dopamine. Apparently cheating causes a rush of a chemical called dopamine in the brain (Google "The anatomy of a cheating brain" - there's a good article there) it's addictive and it seems to me it can make a logical person act quite insane
5) He had a family history of never having to accept responsibility for his actions. His mother ALWAYS blamed someone else when he did wrong, she instilled in him the notion that he could do whatever he wanted and never take responsibility (I've known the man since he was 11 years old, I have seen this in action!)
The one sad truth I have learnt over the last year is this - no matter how logical the explanation for all of this becomes when you dig and delve and discover the "Whys?" and the "Hows?", it doesn't take away the pain. I spent a lot of time thinking that if fWH and I could just figure this all out in a way that made logical sense to me, I would feel SO much better and it would be SO much easier to accept.... Not so. It still hurts like hell, I am still just as angry with him, I still find it all beyond disgusting
That being said, I think it IS important to figure out the Why and How of it all. Armed with that information you can work on the weaknesses and vulnerabilities that led you to this point. You can put boundaries in place,get therapy and talk through things and hopefully prevent something like this from ever happening again.
