Mark, 
Welcome to our group.  I'm so sorry you find yourself here, but I know we can help you through this struggle you face. 

I can put myself in your shoes.  I joined here two years ago facing the same fears.  It was awful being in limbo not knowing if I could save my marriage.  All of those storm clouds of fear and doubt regarding finances and family destruction and living arrangements and parenting and everything else were paralyzing.  I remember it all too well.   They are just storm clouds though..  What you can't see is the good stuff that lies on the other side.  Just remember that there is a happy future and you will get there..  you just have to endure this storm. 

Keep posting and sharing and let us know how we can help. 

If you are near any of these major cities, please consider signing up for a face-to-face meeting group.  Having other real people near you to help out is a huge benefit.  http://www.straightspouse.org/face2face-support-groups/
