I think society’s issue here is not necessarily anything so new. I doubt that women have changed all that much, nor men.
What has happened is that a social contract in which the parties swear promises in front of formal witnesses and include a clause that the contract will be everlasting, can be broke asunder by law without any reference whatsoever to those clauses nor reference to the witnesses. In short, marriage has been turned into a sham while people are still being told that marriage is the way to gain commitment and stability.
Do people getting married mean what they say? Well, my guess is that at least one of them does in almost every wedding and I cannot see why governments insist that marriage, upon which a stable society relies, is the only contract people make solemnly yet which can be dissolved without any relevance to the contract itself.
In many legislatures, there are now ‘Civil Unions’. I suggest that these could be used by those who do not wish a life-long commitment to fixed terms, while divorce and marriage start relating to one another so that those who (wisely or foolishly) knowingly engage in a lifetime social contract are made to hold to the terms of that contract, or forfeit all.
