I can totally identify with still not wanting a divorce AT ALL - but also being completely ok with (at the risk of sounding flippant) her taking her time coming back. As unpleasant as it often is being apart, as much as I miss her (who she was when things were good), there ARE definite positives - personally, financially, etc - to us being where we are right now.
