@thesparrow There are men who don’t cheat. There are different types of cheaters. Chronic ones, and those who find themselves cheating when they had never thought they would. I agree with @coloma that most people don’t cheat for the sex. People like to feel good about themselves and to want to come home. The simplest advice I give women is tell your husband how great he is, be supportive, review your goals with each other so you understand what you both want from life, and when he walks in the door be happy to see him. Girlfriends are excited to see their new boyfriends, they do think their boyfriends are great, boyfriends talk about their dreams with their new girlfriends. Don’t lose that. It’s not that you have to be always positive, giddy, ready for sex, can’t complain about life, nor discuss difficult challenges in life. You just need to set it up that he likes coming home, looks forward to it. That’s what I think anyway. A lot of women reject feeling like they have to kiss up to their husbands needs, that the men are adults, and this puts the wife in a position of having to cater to him in a sense. Him and his ego. I can see why women feel like that, and men might even be offended by the comment, what can I say?
All this is for people who are inclined and want to be monogamous. People who prefer not to be, that is a different story. The dynamic is a little different I think. A happy home life is just as important though. Those not cut out for, or not desiring monogamy need to be honest with their partners is what I would say, because cheating usually destroys trust, respect, and in turn destroys relationships.
How would you know if your grandparents cheated?
