I'm sorry, but if you didn't know what your wife was before marrying her, then you deserve her cheating on you.
She's 100% going to cheat on him. If he think saying he's not into an open relationship will stop her? Especially if she already brought potential candidates?
She only said this in hopes she can openly cheat on you to your face and you being okay with it. You saying no just means that she's going to do it and not give you feedback on what's going on.
It's just like when my parents before would tell me not to do something or get something when I was younger. I might ask first and they might say no. What do I do on days when I find out I have a half-day in school or there's no school that day and my parents don't know? I'm going to that place that they said not to and I'm going to buy that thing they said not to. They didn't know and up to this day they still don't know.
This guy is the exact meaning of a soyboy, a cuck, a beta. I might be an incel, but you know what? At least I have no wife that will cheat on me and even if she gets caught, she can divorce me for the person she's cheating on me with and then take half of my fucking money to give the next guy.
My life sucks, but I'm not sorry to say that if I had a choice between being incel or living with a whore that will cheat on me whether I want her to or not, I personally will rather be incel. Call me a vocel for saying that. I don't care, but I rather have nothing than have something that's getting filled with and covered in another man's secretions.
