It is even harder when you love them so much, when things in the marriage were, by most standards, very good, when it all seems so totally upside down and inside out. People have break downs. What other reason is there? I went back and read some of your earlier posts. They hurt my heart because your words were so poignant and full of pain. it reminded me so much of the early days for me. I loved him so much it nearly killed me.
But it is now 2 years after he left and I am happier than I have ever been. I hope your situation is different and your H comes back to you, but even if that doesn't happen, life can begin anew and happiness can be rediscovered.
