I feel very badly for you, but just think, sometimes, (most of the time), things work out for the very best!! Yes, that is difficult to realize at this point, but please keep your chin up, keep smiling, and try to correct some of the things about yourself that might have caused your wife to leave...
None of us are perfect for sure....
I wish you the very best, I know that we haven't met and talked before, but my heart goes out to you.
