Likewise, a man is not obligated to deliver himself up for a disobedient, wicked wife whose very actions reflect her lack of faith in her husband.
Apparently, you didn't see this Bible verse in the correct whole context.
Sorry, but you are dead wrong.
And you have most definitely proved that it would not be prudent for you to marry until your error is corrected.
Christ delivered Himself up for souls..the husband and wife deliver themselves up for each other. Both the husband and wife have a spiritual duty to get each ones soul to Heaven. It is a Life’s Mission in the Marriage State.
If one of the spouses fails and turns to a life of sin (or minor faults/overall weakness) it is the responsibility of the other spouse to obtain the grace on behalf of the failing one to merit their conversion back from error.
This is a very simple fact of Catholic Marriage, and for you Croix it is completely missing from your sense and understanding of the Sacrament of Matrimony and the Marriage State. Prenuptial agreement and financial stability be damned, it is the soul of the spouse and their eternal destiny, that is what matters.
