Socially and legally women aren't held to account for breaking their commitment to a man, divorce doesn't carry the same stigma, let alone relationship breakups. Its even become the norm for women to practice serial monogamy, the idea of jumping from partner to partner, while the idea of "settling down" is now quickly becoming a radical sentiment. Women have so much more opportunities to easily opt out of commitment, whether its no fault divorce, abortion, I mean society literally pushes women to pursue careers, become financially independent, so they don't have to rely on a man and they can always have one foot out the door.

Society doesn't allow women to be held to any standard for breaking commitments, even if a wife cheats on her husband, the only course of action he can really take is divorce in which case its very possible HE can be significantly financially penalized for doing so. Society has even gone a step further to put this risk on men even if they aren't legally married, so that if a couple has been together for some time that they can be recognized as being in a common law marriage and treated the same as a legally registered marriage, such that the man can suffer the same consequences if he leaves.

Many will try to argue, "well these aren't gendered values, policies, and laws"... YES THEY ARE. Because the way humans pair up, they naturally default to biological gender roles regardless of society, women naturally go for men who can provide more for them. Thats why in divorce courts men are overrepresented as being the providers of alimony, equalization of assets, child support, etc.

Edit: Lot of people triggered in the comments, asking why I'm complaining. I'm simply addressing a common complaint of women, you'll see everywhere women complaining that modern men lack commitment.
