What's the goal here?

 This goal of forever and ever marriage has caused so much and many problems internal to religious organizations.   It seems to me this going back to cherry-picking the laws in the bible you want to follow and ignore the rest.   Do we follow and enforce the marriage mandate but ignore the stoning for planting dissimilar crops next to each other.  They are both in the Bible as Laws.  So do we liberally apply interpretation to the stoning but enforce the Marriage mandate. It strikes me that you must apply the same interpretation of all that is delineated in the Bible that same and not picked to interpret and apply to your life one way those things you like and understand while ignoring the rest.  

The first marriage I thought was forever, it lasted 18 months as I realized I did not love her but loved her money.  I left the marriage in guilt and shame.  My second marriage was forever and ever until I realized we had nothing other than I married her for her sex drive and her model looks.  Yep, I was gone after three years of horrible guilt and realized I was shallow as all could be.   

Then when I was not looking and not expecting it I did find the forever and ever love and partner.  After 35 years I am more in love with her than on the day we married.  It has not been easy and has taken work, but it has been worth every minute I get to spend with her.

So I think the goal is not strictly to stay with a person once married but to take the time to find the one you can stay with for life.   The goal then is the journey of faith to the life mate that will journey with you in faith.   Just an old guy's humble opinion.
