Sex isn't the driving factor.
Oh, I think for some of each gender, it very much is.
I agree (of course). But I also don't know why it's so difficult for others to believe that someone would cheat "just for sex". Ugh.. Sex is a FAR more potent motivator for me, and I suspect for many others than "You're so smart RIO" or "Can I come fix your sink RIO" or "Here's a new watch RIO". It's so much more powerful that I even have trouble making the comparison without some brain pain. And yet, many seem to insist "It's the kibbles", a motivator that to me personally, seems ridiculous compared to sex with someone new. Kibbles have almost no value at all to me, sex is high value, sex with someone new is VERY high value. Why is it that "the kibbles" are considered by so many to be more "the reason" than sex? I suspect it's primarily because they aren't motivated the same way I (or many men I know) are by sex, but, trust me, we exist (those of us who are highly motivated sexually) and, if my experience is anything to go on, there are a lot of us.
This kind of reminds me of conversations I've heard/read about how "no woman wants to be a prostitute". Well, really, are we sure about that? Sure, it's not a great job, but it pays very well, and, believe it or not, some women do enjoy sex with lots of different men. There must be something else, something wrong with her, something broken inside of her. We don't say the same thing about a guy who's an underground coal miner though, a job I'd care for a LOT less than being a prostitute. Or the garbage man. Or any other profession that involves terrible working conditions, far worse than those of your typical call girl. Sure, taken to the extreme, nobody wants to be a prostitute, just like almost nobody wants to go to work in any profession at all, we all just want to be rich and retired. :)
You say what your wife did to you is more hurtful but a sex-only affair would be a dealbreaker.
I think I explained it, but I'm not claiming this is logical, it's just my personal thoughts on it. A sex only affair from my W would be "too dangerous" to R from for me personally. Simply put, an A would have given her exactly what she wanted (sex) in massive quantities, in exciting situations, with someone new. She would have tasted the forbidden fruit and figured out "this tastes great". She'd be unsafe because logically she'd know "great sex is on offer in an A" and, if that was her motivation, that would be difficult to live with. Kind of like the reformed drug addict working in a pharmacy, the temptation is likely to be too great because, yes, the pharmacy does have all kinds of drugs in it, and yes, it's right there for the taking. I'm not claiming this is logical, I'm just saying how I feel on this particular issue. I'd understand it, yes, but I'd also consider her an unsafe partner moving forward (and honestly, if you must know, the men I know who do this would absolutely be "unsafe partners" in my eyes as well.. No double standard here, just applying the same criteria to both sexes).
You say you're savage on WH's but you apparently regularly spend time with them and discuss their sketchy personal lives. You take WH's word for it that their affairs occur for "understandable reasons" (FYI - this sounds a lot like 'justifiable reasons' ) but do not take your wife's word for it when she says she felt like she was "in love".
Not anymore I don't, at least not when I can avoid it (which is most of the time). I did, yes, before my W's A, spend time with those guys as part of my job.
No, understandable reasons are NOT the same as justifiable reasons. I can understand why 2 gangs start shooting at one another; it's stupid as hell, yes, but I understand their motivation. I do NOT say it's justified, NOT EVEN A LITTLE, but I do understand the thought process. The guy who just starts shooting into a crowd of people he doesn't know? That's not at all understandable to me and also, similarly unjustifiable.
Here's what it sounds like to an outsider: I believe men but I don't believe women. I also think men should be punished harder and women are loony-bin innocents who get taken advantage of by tail-chasing men.
I believe women who say they had an affair for "love". I just think it's a real stupid (for either sex) because that's not what affairs offer. I also believe people who have exit affairs, they are really looking to leave the M. Again, a real stupid reason to have an A, but I do believe that's their motivation. People who have A's for sex, well.. It's not a stupid reason to have an A. You rob banks because that's where the money is. "I want money" is not a stupid reason to kick in the door of a bank, even if kicking the door of the bank in is a REAL STUPID thing to do. The reasoning is sound, even if the actions are incredibly stupid/hurtful and massively damaging to other people. Just like the gangs shooting at one another, stupid as hell, people die, but the reason the shooting started makes sense.
And yes, if I'm honest, I do think that at least some, and, IMHO, many WW are "taken advantage of" by tail chasing men. But it's not because men are bad and women good, it's just that men are typically the pursuers in relationships, normal or affairs. And if your pursuing for an A, there's gonna be a LOT of lying involved, manipulation and misdirection, it's just part of the dance.
