I came upon your websit looking things related to happiness. I am a biologist and vary much into evolutionary psychology. I am a born and raised European but the last half of my life I lived in the Caribbean. What bothers me about this site is that cheating in a marriage is almost automatically coupled to a personality disorder (narcissism in this case). I have never met a male this did not "cheat" once and a while. I did it once and I think I had a very good reason for it. I mean, is "cheating" always a bad thing? Isn't is maybe something that comes with life?
