JJ... Regarding the separation idea, there was an article in the wall Street Journal last week which discussed some positive results with a concept called " controlled separation," where every last detail is spelled out in contract form ( including dates/and or sex). The article pointed out that separation often leads to divorce because there is no real support or direction. In the controlled method, lots of paramenters are discussed beforehand and the idea is to give partners a time out.
I sometimes feel my H and I would benefit from something like this, just to clear our heads and strengthen ourselves as individuals. What stops me, apart form organizing such a move, is that we would probably regress pretty quickly once we were back together, just as if you went to a contorlled-diet spa and then came back to the real world.
