Asking whether Jesus meant to be taken seriously cannot be the more helpful question.  For if Jesus intended his words to be taken literally, then that disposes of the issue.  For we say, God's will, not ours be done.  It also goes without saying that Jesus intended that we take him "seriously."  You keep talking about the "reign of God," as though taking Jesus literally is necessarily alien to that.  That's illogical.  

You also talk about the subordinating God's command not to divorce to the command to love God, love thy neighbor.  They are not inconsistent.  God doesn't give us inconsistent commandments.  In fact, as I have told you, Jesus said, "If you love me, you will keep my commandments."  Your new-age theologizing is hopelessly illogical on several grounds, is counter to Scripture,  and has been rejected for centuries by the Church.
