LT - if you stop and things go to hell, you can find another counselor. Leaving MC doesn't mean that you can never ask for help with your marriage again. MC isn't the only person who can help. In fact, someone else may be able to help so much more.

I think spacing out sessions and weaning yourself off him is a good idea. I would also encourage you to openly discuss that you are planning to wean down until termination. I think it's important to spend some sessions tying loose ends and "winding down" so that when termination comes, you can feel the chapter is closed, not incomplete.
