Stay detached, mysterious, interesting. Busiest guy in the room. Look good/smell good. Courteous, even engaging, but not NEEDY, not "MELTY MAN" and not PURSUING.
Make sense?
Let her come to you. And when she does, your answer is "Hmmm, I'll have to think about that. I'm not sure how I feel about that (getting back together to work on the marriage) anymore." or "I'm afraid it's not that easy anymore."
A wayward wife losing her attraction for OM1 is only 1/3 of the battle, Arc. If you don't RE-attract her, by working on your GALing and your self-improvements, she will more likely turn to an OM2 than she will to return to the marriage.
Arcola, go back and re-read your old threads. You've been given exceptional advice by both men (Theoden, Jefe, me and others) and women (Train, Twinmom, a RARE appearance by DB success story Pearlhrbr, and others) alike, and it was actually pretty alarming to re-read and notice how you virtually IGNORED ALL OF IT. People would post to you, suggest books, ask you questions, and you wouldn't respond, you'd disappear for several days or weeks, and then just sudden resume posting with "So an update . . . "
What is is you want here? Are you just venting? That's fine if that's what you want to do, but it's NOT going to fix your marriage.
I'm done wasting my time. All of the advice I've already given you is there if you care to re-read it, once you're serious about trying to save your marriage and your intact family.
