I wouldn't go so far as to say let the M die like 25mlc is saying. Rather, let your loving thoughts of your W go. The M is only the circumstance. Even if you did get a D, your W is still going to be around. She's not going to poof go up in smoke.
In your mind, you need to let her go. If not, whether you're married or not, you're going to still be following her around.
Like what was said earlier. If you're going to do anything, move back, stay away, whatever ... do it for you and stick to your guns. Only then are you going to be able to move on with YOUR life.
M-43 W-40 2D - 9 and 5
Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
