I understand. As men, we are problem-solvers and "fixers," and when we are told we have to "detach," we equate that with "doing nothing" and we lament the loss of CONTROL over the situation.
In other words, we feel "Man, if I could just SAY THE RIGHT THINGS, DO the right things, in the right combination . . . I can 'fix' her and this situation."
ERRRRR!! Wrong. It doesn't work that way.
Give her to God, and give her over to her own decision-making. You cannot make this choice for her, brother. She gets to decide (but then she also gets to be accountable for her choices).
Passivity sucks, I know. Limbo . . . sucks. But it is what it is. All you can do is pour your "fixer" instincts into NEIL.
