This thread has been fantastic.
I just cannot believe all these smug comments saying "ohhh I trust my DH so much, he can spend time with whoever" ...
I can possibly imagine 2 reasons why anyone would say something like this, sorry if it sounds awful but here goes:
i) DH is unattractive, unsuccessful, doesn't have much spare cash or charm and is generally only interested in beer;
ii) if above doesn't apply, and DH is attractive, stylish, well-heeled and influential in his circles, AND his wife still insists that she doesn't mind him spending a day out with another woman, then the wife is deluded.
In case of i) above, these men don't have affairs not because they are so righteous, but rather because noone wants them.
Successful, intelligent, interesting and rich men do tend to have affairs a lot.
We only need to look at businessmen, sports personalities, politicians. But we don't need to go that far.
I work in the City in a predominantly male, highly paid / professional environment and I am close to quite a few of the male colleagues, enough to discuss personal stuff. Each man I know has had at least 1 affair that I am aware of. Some had a few and/or use escorts on a regular basis.
There is one exception but this is, perhaps to some extent, because he is particularly religious. He doesn't drink or smoke or gambles or swears either.
Oh, and remember, Jennifer didn't mind Brad Pitt spending time with Angelina Jolie. We all know where that ended. A cliche of course, but it's precisely the point.
So, all the smug wives of unwanted (by anyone but themselves) DH, please give it a rest.
Given a chance to engage in a no-strings affair with a beautiful woman, not many men would resist. Those who do resist would do so, more often than not, for religious reasons, or because they are simply scared (scared of being found out; or, often, scared of not being able to perform!! Yes, the common worry apparently with a new, exciting partner).
My advice to the OP would be to watch her DH closely, burying her head in the sand isn't going to help. If she still has the power to stop this developing into a full-blown affair, then shouldn't she try and save her marriage?
Not my real name/wouldn't want anyone to guess who i am.
