Sorry for your pain. Hang in there. There may be hope. At some time it me be time to get out. Set the example for your kids so they see you as reasonable, if you can't save your marriage, your example through this will make an impact on them.

You quote John 17:26 says "and I have made Your name known to them, and will make it known," ... think about it though ... where in the Bible is there evidence that this was literal? Where in the Sermon on the Mount did Jesus take any opportunity to make the name Jehovah YWHW known? Not a single mention! Of all opportunities wouldn't this have been the one?
... or, perhaps, just as God's name was made known through Moses (not literally, but by action ... check out your Insight book) it was defined by Jesus. Jesus name = Jehovah is Salvation or Jah Saves .... so the name of Jesus makes God's name know as salvation, not a literal making it known, but defined.
