We obviously have different understanding of "cheating" and "love"
For me is much more worse when a parner confess more, spend much more time and talk more with friends instead of with the signifiant other (things that happens in so many couples) - than doing a bizare fantasy for 15 min every 6 months from impulse/psy problem
It s like somebody is addicted to gambling, comes on a psy forum for support/advices for treatment - and I say to him "you spend all the family money, you deserve to be alone" etc
Or somebody that has depression and obviously do not talk much with her partners - to say to him: "you ignore your partner, you are so selfish with your internal problems and do not think about your partner, you deserve to be alone"
