Name change because I don't want my other posts raked over.
I've been cheated on repeatedly in the past found myself single. I know why that happened to me now.
There aren't "plenty of lovely single men" it took me 2 years to find one that wasn't a dickhead. Dating in your 40s is absolutely brutal.
70% of the men that I spoke to on dating sites were in relationships already and some hid it magnificently. Eventually you suss them out, they beg (literally BEG at times) for you to just meet with them for a coffee.
The "lovely husband tempted by an evil scarlet woman" is a very, very naive way to look at it.
As PP have said, happily married people don't look elsewhere.
There's a lot more sexless marriages out there than people will admit to. (I was in one
)
Life isn't black and white and neither are affairs.
One guy I chatted to didn't want sex, just attention. His wife still co sleeps. The child is 8. He sleeps on the floor in the lounge. That is his life now, I'm guessing he didn't enter marriage expecting that. She refuses to address it, he doesn't want to leave his beloved daughter or the family home.
I think this topic evokes such anger and vitriol because people are aware that they aren't necessarily in happy relationships.
If you're worried your other half is going to stray why aren't you working on your marriage?
Men unfortunately are quite sex driven. Maybe modern society needs to drop the religion based "sanctity of marriage" and be realistic.
If it's not happening at home, it might be happening elsewhere.
