So God would rather see two people stuck for their entire lives in an unhappy marriage because the initial love that they felt for each other has disappeared and they both fell in love with other people from their workplace, than two divorced people who will remarry and live happy lives alongside their new spouses?
"Intial love." That's always a lie. "Initial love" is nothing but reaction to physical stimulus, a rush of hormones. Anyone who has been married knows
that always wears off in a few years.
But God tells men:
Husband, love your wife
and
Rejoice in the wife of your youth
These are not hopes, these are
commands.
Remember that in those times, whether Jew, Greek, or Roman, nearly all marriages were arranged by the parents.
"Wife of your youth" meant the wife the man's parents arranged for him when he was young, not the later wives he may have selected for himself.
So everything scripture has to say about the permanence of marriage is being said about arranged marriages. There was no "initial love" such as pop songs and rom-coms wax enthusiastic over today.
After being married for 34 years, watching my marriage and the marriages of others, I have learned that initial compatibility is nice, but
all people change over time.
All people change.
Regardless of your initial compatibility, in ten years, fifteen years, twenty years, both will be different from the way they were when they met. Sooner or later, they will ask themselves, "Who is this person in my bed?" And they will be no different at that moment than any arranged marriage.
Unless as they were changing, they made deliberate effort to
change in the same direction.
Love between a husband and wife was deliberate, intentional, created, worked for, maintained, cherished--"for better, for worse, for richer, for poorer, in sickness and in health."
The truth is that any Spirit-filled Christian man can be a satisfying life partner to any Spirit-filled Christian woman, and
vice versa, but they both have to relenquish the individual selves they were before they cleaved to one another.
I think you're misinterpreting Christ's teachings. If by "His bride", you mean the Church, I invite you to look at Revelation 3:16, where Christ clearly states that He will repudiate "His bride" for not being the way He wants her to be - meaning "hot". If Christ will abandon his bride because His bride doesn't have the right feelings for Him, why would two people stuck in a marriage in which neither of them have feelings for each other remain bounded together only to endure the toxicity of living alongside someone whom they don't want to be with?
You misunderstand the passage.
First, there are several "churches" listed in the chapter and messages to the churches. You want to call out one message and call it a "repudiation of the church," yet ignore the immediately preceding message. That's pretty tight cherrypicking.
Second, Jesus says to the Laodiceans that He'd accept them as
either cold
or hot. This is a repudiation of their being undistinguished from the world around them. An example:
When I was active duty, on my very first full day overseas (in Thailand), my mentor took me to a little restaurant off base for lunch. They had a buffet table set out with breads and sliced meats, but my mentor walked to a table and sat down.
We waited for a few minutes for a server. I began to get antsy, and suggested just making sandwiches from the buffet.
My sponsor said, "Oh, noooo! We don't want to do that. There's no telling how long that food's been sitting there. It might have been there since Tuesday."
Then he leaned toward me and said, "When you're eating overseas, here is what you have to remember: If they take it right off the ice, it's okay. If they take it right off the fire, it's okay. But if it's room temperature, spit it out. It'll kill you."
This is what people even in Jesus' time knew, which is why He could use it as an example. Kept hot or cold, food stayed edible; left to settle to room temperature, it became toxic.
Compared to the world, a Christian may seem "cold" because he is not excited by the pleasures of the world that excite the world. Or a Christian may seem "hot" because he does get excited over obeying Jesus, which the world does not understand. But he should never be like the world.
