That's one way to interpret it, however, I interpreted it as the man trying to think of anything he can do to break up his wife's relationship with the other guy. That's not going to happen.
Yeah, you probably have more insight in that area. And I agree, it's not going to happen. Wifey should also realize that expecting her husband to put up with her openly having an affair is emasculating.
I think Dad should document the hours he's spending as primary caretaker of the children, and realize that the children are suffering from Mom's behavior as well. *Someone* has to take care of the kids. Would he prefer it be Wifey and her par amour? Ew. Just ew.
I used to be friends with some in OP's situation in NYS. The friend chose to leave rather than sharing a bedroom, and didn't file for years because of the house issue - idiot just continued paying the mortgage while renting a room, and going over every day to take care of the kids until "wifey" got home at 1-2 AM. I say "idiot" because he did this for years.
By contrast, a relative was shocked that, after she moved out to "find herself"
leaving the kids behind, her ex husband got both house and kids.
