When you really get to this point, where you can't go on like this, tell him calmly and lovingly that you simply exhausted all your resources, that you are not fit for the role of a friend in such a setting, that you now move on.
But after reading your long thread wwith your whole story, I suggest that youdon't do it: keep the changes, enjoy what you achieved so far. You did a tremendous job, and you did it very well!
Remember that all small and bigger changes have to accumulate before a breakthrough happens.
