"I would suggest that taking Jesus seriously is more important than taking him literally."
****

It depends on the text.  Taking Jesus literally regarding plucking one's eye out certainly wasn't his intent, but he certainly meant to be taken seriously.

You say "a rule is not be enough," but you fail to distinguish "enough" (sufficient) from necessary.  Following Jesus' rules is necessary.  It may not be enough, but it is necessary.  More illogic and false teaching from you.  Since the time of Jesus, the rule on divorce has been what he said it was.  

You say, "Indissolubility has never been the simple rule that you prefer."  It IS a simple rule.  Hard to follow, but simple.  And it's not the rule I prefer; it's the rule Jesus gave us.  You prefer your own rule, and that's understandable.  I prefer your rule, too, which is that divorce be permitted for cause other than adultery.  That would be MY rule --- and your rule.  But I don't pretend that my rule is the same as Jesus' rule.
