What you are saying is essentially and eventually biblically true. And I will discuss that.
But still the scriptures and terminology that you are using to get there are inaccurate.
The word fornication is a man-made ... man-formulated Latin word that was inserted into the older translations of the Bible.
Even at that, it did not mean single people having sex. It was referencing to prostitution and then Christian customs redefined it as single people having sex. Which if you understand.... that does not make sense, because in the biblical era, people had sex to form a marriage. No biblical requirements for weddings and vows.
The Gospel account of Christ (a Jew) having a discussion about Judaism (the Mosaic Law) with Jews, this discussion is not about Christianity. We do not know how many wives they had. Christ was modifying the Mosaic Law? There is part of this that I do not think was in the original scriptures because according to Mosaic Law women were not allowed to divorce their husbands, they were property. If they ran away it was automatically assumed that they had committed adultery and could be killed. From the conversation, what Christ said, did not go well....even with His own apostles. But near to irrelevant to Christians. Christianity did not initially adopt the process of divorce. The word divorce does not appear outside the Gospels....from Acts to Revelation the word divorce does not appear. If that word appears in your Bible between Acts and Revelation it is a mistranslation.
Paul discusses couples breaking up and or separating in 1st Corinthians chapter 7. And what he says is pretty much the conclusion that you "guys" have come up with....the only reason for divorce is infidelity. But there was no "Letter of Divorcement" discussed and the word divorce is not used and there are no courts to hear divorce cases. Civilly women were not allowed to legally divorce their husbands until 1857. They just walked away....some call it put away. Either way the Bible is very strict on this.
Putting it into perspective...the Bible does not take a lot of things into consideration....You are not going to hear of a husband rapping his wife....or beating his wife....or doing the same to his children.....because they are his property and these things are not considered justification for leaving there husband....only infidelity. It would be a long time before these things were a concern for anyone. So if you are a fundamentalist it is a difficult premise, particularly for women to allow themselves to be locked into such a relationship with no escape....or then to never remarry....alone for the rest of their life and their children not having a father in the home.
Now I am not a fundamentalist....so I admit I do not agree with this and I do not agree with slavery. I have very simple concepts with how I conduct myself in relationships...I respect women overall, I treat my loved one with respect and love. I believe that people that are in love should be married and people that are not in love should not be married. I believe that men that abuse their wives should be beat. My step-dad shot my mom. By the time I got done with my step-dad, he was not able to work another day in his life...
It is a matter of beliefs but I feel sorry for the women and children that are abused.
