Together 13 years swinging for 5, kids don't know and it is rare, perhaps once every 3 months? It seems the wife is exclusive to this OM physically though I think still chatting/flirting with other guys, but tbh I don't know.
She met the OM with out telling me till after and spent 3 weekends with him, She may have spent last Saturday with him I honestly don't know. I have stated that as far as I am concerned she is having an affair and she has said she is just enjoying the freedom and has no feelings towards him other than freedom, having fun and new experiences, she is insisting on concerts, trips away and 5 star hotels all the way. I doubt she has told him about her having 3 kids but perhaps she has. He is 25 and a physical specimen borderline fitness model.
What's the odds this 25 years old physical specimen is being loyal and dedicated to your wife only?
Consider that. The odds are less than 25%. The age range tends to cheat, and cheat in relationships where there is not a marriage. Knowing that they are boinking a wife, they will play the game almost automatically.
She is likely one in his harem. You might help her out by letting her receive information to prove she is only a bedroom lay to her, because he has others. And even more if she is not the "top" one in his harem she will be outraged.
