Oh damn...that so sucks Binxgook
Everything that comes to mind sounds like a cheap cliche'...
So, I'll just say...be strong buddy...and don't let your pain overwhelm you to the point of doing something you'll regret.
I spent over 25 years with the same woman...got divorced 7 years ago...at my own instigation. Even though I was the one that wanted out, still a very painful process to see a relationship of that many years die
Okay, perhaps one cliche' after all...
As old doors close....new doors open...but you do have to open them. Hang in there Binx.
