Just read the thread again. Sorry to hear man. Nothing I could say would really help, other than life does go on eventually.
My bro's first wife left him all of a sudden for no good reason after he did everything for her. Totally classless the things she did. He was pissed for a while, pissed at himself (blamed himself in that totally illogical way), but got dating again, met some nice girls, got his confidence back, and eventually found a really nice woman who became his 2nd wife. His first wife eventually got fat as a house.
I never liked his 1st wife, and things worked out for the best, even though it was the roughest road to get there. Good luck bro.
