So I've seen many people around here saying that women are "hypergamous" and can't be trusted. But can it really be interpreted like that? I mean would you not be at least slightly tempted to dive in, if a girl approached you on her own, and she was really hot, regardless of your own marital status? (and especially considering the current state of the world)

Who do you think is more to blame from your own life experiences? Would it be the guys, who often just let their guard down way too much, and then it's not surprising if their girlfriend cheats on them? Or is it the girls, who don't/can't restrai themselves and go with the flow?
