Generally women will list "cheating" as a dealbreaker (although most women will fall more in love than ever, or at least more in lust, with men who cheat on them) but it's assumed that women generally want monogamy. What could be better evidence of the natural solipsism of woman?

Before you say "But STD!" just keep this in mind: how many women would agree to a harem-like arrangement, where they got to have sex with their dream guy (and be financially provided for) but when she was at work, or busy, he was fucking someone else who was 100% guaranteed not to have an STD? The women would STILL say no, and it boils down to pride and solipsism, the woman's most natural traits.

Truth be told, you can love two people at once and having sex with a mistress doesn't mean you don't still enjoy sex with your wife. A man having an affair LITERALLY CHANGES NOTHING FOR THE WOMAN, assuming he is clean and not financially draining her for the sake of the other woman. But women will still claim "betrayal" or claim that this is some huge moral problem for them. But why? Nobody gets hurt, other than the wife's precious ego.

Before you say this is a double standard, men SHOULD want a monogamous woman, because they have to worry about the paternity of their children. Women don't have that concern.

I'm not saying that women are bad or anything, just different from men. But isn't women's insistence on monogamy just more proof of the fact that everything in their life- be it a post on reddit or their husband's affair- has to be ABOUT THEM?
