It doesn’t actually go both ways. It’s, usually, an open secret that the young men are dating.
if it ever become obvious, it’s simply denied. The same as men who continue to see their girlfriends after the marriage, are turned a blind eye to.
Do you really believe the 2 men your friends married didn’t have some agency in those marriages?
Men, often, get more say in the marriage. And have more freedom after. The chances this man’s wife would email their ex looking for attention and sympathy are extremely low, because there’s far more risk to her. If he cheats do you really think he faces the same consequences his wife would?
And again, I will say what I said above. Yes many people in these marriages are miserable. That doesn’t entitle you to keep trying to pull someone from your past into the middle of it. Especially, when you messed them around for years in the first place. When he knew all along how it was going to end.
It’s sad if he is miserable. That doesn’t mean what he is doing to the Op is fair or right. She is not obligated to be support for him because he isn’t happy.
and you do realise there’s a good chance he is reaching out to the Op in the hopes of rekindling their romance. Which would have Op in the position of OW. He isn’t going to leave his wife. Again, men having mistresses in these communities is an open secret and quite common. Not everyone does, obviously. But where it is happening, people often know and pretend they don’t.
It’s really not the same.
