Also, thanks for sharing about the church, and her resistance in supporting some the things that church believes sets you apart, outwardly, from the secular world. After moving to another church, could you see any outward evidence that she was growing spiritually, or was she about the same? I don't know if part of her rebellion began in the first church, but if she felt pressured by any of the members.....and especially by you, I could see her keeping that resentment.
Anyway, getting away from the spiritual side for a bit..........what has been done to help your son with his anger issues? If he still feels so angry at her, don't you think their R needs to be in a better place, before you start trying to draw her back into the MR?
Is he attending anger management, and IC?
I think I may have already mentioned how important this family needs the help of a qualified family therapist.
I just encourage you to not apply pressure to your W. if she felt pressure by the church, and pressure by you........it could have easily affected her feelings toward you and the MR. It may be what is holding her back, and not wanting to submit to any authority that tells her what to do. Know what I mean?
I have to stop here, but keep posting and I'll return.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
