Idk lol I鈥檒l have to think about this but poor impulse control? Selfishness / lack of appreciation of their partner (if their partner isn鈥檛 an awful person)
I could also see someone in a position where they can鈥檛 leave a relationship with an abusive person and then cheat on them (but I doubt this is common bc there鈥檚 probably an element of controlling the victim etc + the victim would probably not want to do this either bc if the violence is bad enough it could lead to murder)
Idk ^ boredom and lack of appreciation are good ones. Idkkk so selfish to your partner. Maybe the person is looking to get out and just hasn't fully committed to the idea yet.
People cheat because they feel like they do not get enough attention/sex etc at home. Usually pent up aggression after trying to speak on the matter and being shut down
Cheating with wife-boredom something new
Cheating on test-thinking it won't matter in the long run which it probably won't
Cheating on tengaged -thinking it's funny when it's really not
Because human attraction goes beyond and has no attachment to human love. You can love someone and want to fuck someone else, that doesnt mean you love that first person less. You just feel attracted. Not love.
I must agree with Hunty
My revision would be that humans can work out a monogamous relationship if and only if both parties (sincerely) agree that acting on sexual interest in anyone else would be destructive, and consequently just keep to themselves
