Yes I want to second this.I just want to remind the members that BroHus admitted he had dropped the ball in his marriage. He put himself first. He withdrew and wasn't an involved father. He allowed himself to be "complacent and comfortable" (whatever that means). His wife got burnt out, felt ignored, and took a lover for comfort.
So, it's not just that she cheated. It takes two to tango. We don't know how often she reached out to BroHus for love, comfort, help, entertainment, and yet he dropped the ball.
My point is, this whole thing is not just: "Wife is a cheating lying selfish liar!" She sounded kind of desperate for comfort and adult companionship and to feel treasured and valued, not just "the wife," "the kids' mom." I can relate to this. I went through it myself. Many many women do.
It should be a warning for all the men who want to open their "sexless" marriage. Make sure that you are a good husband because opening your relationship will mean your wife gets to see what other people are like as partners. It might not be that she meets a guy and replaces you with him. But she may see how attentive other men are to their families as well as having other partners. Your flaws will be on display.
I think that's what could be happening here. The other guy is more in tune with what she wants now and is encouraging her not to fall back into the same rut she was in before.
