Health,
First of all, yes, I do believe there’s chochma by the goyim.
That said, there are fundamental differences between us and them about what marriage really is about. We get married for different reasons than they do. We STAY married, sometimes, even when its not going so well, for much different reasons. (I’m not talking about in cases of abuse c”v).
Bringing children into the world and raising a family is our primary reason for getting married. Their primary reason is self-fulfillment (psychologically very selfish).
Big difference.
