I was happily married to. More so, I love my W to death and have for about a decade.
Like Ralphy I was so happy that I had to be high every night to get to sleep (but that was about work), I had to drink from Wed night through Sunday (but that was about work), I was terrified that my W was going to leave me any day (but that's about my own abandonment issues), our sex life was often a mess (I was just scared of intimacy), but the last six months before she left were the marriage of both of our dreams (she "moved on" six months prior).
You see? There are parts of my M that I would kill for. And parts that I see in hindsight were clearly broken. That's why you have to walk away from it, work like a dog on yourself and your 50% of it, and hope that she does too. Then and only then do you have a chance of forming a new relationship at this point.
