((BBJ)),

I feel for you...man do i feel your pain...it brings back some bad memories of the not too distant past.

Wish I had some words of wisdom that you have not heard yet. You are both miserable together so some time apart may be what the doctor ordered (for you anyway), For him, my guess is OW has resurfaced....that is what happened in my case as you know. That is my experience....if OP is not out of their system the chances are slim and none.....and Mr. Slim just left town.
What I am trying to tell myself now and it may be a propos for you is the following. Do we really want to be with the people that our spouses have become? Yes the children are involved but how strong would our marriages and families be even if things worked out? There has been an awful lot of damage done in the past year or so....I think we have given it a hell of a shot. It is not neccesarilly over but...status quo is / was not acceptable and something needs to change.

I am sorry the present outcome is not what you were hoping for but somewhere down the line who knows.
