Perhaps we just have a difference of opinion.  I've given you all the reasons I have, and you have done the same.  We don't seem to be making much progress beyond that exchange of views.

Let me give an example.  In support of your view on rules you cite, "If you love me, you will keep my commandments." Correspondingly, I cite what Jesus said about the Great Commandments: love of God and neighbor are "all the law and the prophets."  What this tells me is that there is a hierarchy of teachings.  This is also what the Church teaches.  

We are to love as Christ loved us.  In your interpretation of what Jesus said about marriage, the "rule" which you put forward fails of love's purpose in a number of circumstances.  Two examples are given by John Paul II in Familiaris Consortio #84. The point is this: if you treat your "rule" as absolute, it is contrary to love.  Ergo, your interpretation fails to "keep my commandments."

At least that's how I see it.
