Thanks for helping tone things down.
> Would you agree that current society is not as conducive to long-term relationships?
There can be great value in long term relationships, but equally, there is great value in people's freedom to associate (or not), including the freedom to move in and out of personal relationships.
Those ideals could be framed as appositional, but they are synergistic.
Emphasizing only long term commitments, and stigmatizing break ups, has a long history of trapping countless people in abusive, unhappy, practically harmful relationships. And covering up that harm. Anti-breakup effectively becomes anti-transparency and pro-abuse.
Promoting the freedom to break up (not promoting break ups), helps people get out of bad relationships, and gives them another chance to find one.
So win-win.
So yes, I would say that a more free society is tautologically less conducive to long term relationships than one where they are highly prescribed.
But more conducive to people taking the health of their existing relationships seriously, and for finding a healthy relationship, however long that takes. And more conducive to people who are simply happier without a relationship (after suffering a bad one, or not), to do so without stigma.
