You cannot live on the hope your W might want to get back together. Right now that is not an option. You cant just live for your kids. You cant just live for things you "hope" will happen.
We know that's right, but it's easier said than done. It's hard for some of us to imagine life without our wives right now.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
