Wife admits to cheating thoughts in ch1, doesn't matter if it turned out to be him. Also despite seeing how hard he goes into it she admits to being lazy AF with her own self image in chapter 5 regarding the bra top (and you can just see it) . It's like Bruh, if you look cuter than your wife either you chose wrong or she's doing it wrong. Dude could literally divorce her and marry himself and he'd be trading UP! Lmao
Actually that'd be a funny development. Husband NTRs his wife with himself. "After cross dressing again I've realized the disparities between us and they're irreconcilable. I'm leaving you." cue sobbing wife as she loses basically two people (well actually does she really care about the husband or is he only a base for the "person" she really likes now which is his cross-dressing side)
