MB...don't feel hopeless about things. Sometimes there is nothing to be done except wait. It's not that you're giving up or not making an effort. Waiting is an active choice to give them time because you know they aren't ready. Six months ago, my H was not responsive to ANYTHING. Now he is much more receptive (more often than not, though he still has his moments). It's often not about what you need to do, but what they need to work out for themselves.
And NYGal...so glad you didn't feel criticized by us! And you are absolutely right...you DO have to leave them a path home. As long as we don't run after them and try to drag them by the arm...darnit.
