Spend time thinking through your relationship and try to figure out where it started going wrong.
Ask her what she thinks of the ministry, and the idea of A New Beginning, Marriage Renewal Retreat, the After-Care program, etc.
And if you are really willing to keep doing these things, it can show that you are really willing and trying to truly make lasting changes.
She is in critical condition emotionally; probably experiencing what she considers to be an extreme level of emotional pain, akin to trauma.

Understand that , trust, and openness to make amends will be the main ingredients that can save your marriage again and make the task of moving back in after separation a lot easier.
