It's the idea that if you love your husband or wife but you still are attracted to other people, there's something wrong with you, there's something wrong with your marriage, something wrong with your partner.
Protiv ideje da ako volite svoga muža ili ženu ali vas i dalje privlače drugi, da s vama nešto nije u redu, da nešto nije u redu s vašim brakom, s vašim partnerom.
