I agree with Jack. The final say has to come from the LBS themselves.
But that doesn't mean that you can't try to get people to see the light of day after awhile.
When I finally accepted that my marriage was truly over, and there will never be or do I ever want another husband/wife relationship with my ex, I finally stated to heal and put total focus on my own self.
Sure there are some spouses that come out of this, but I believe the majority won't admit what they did was wrong. The statistics are just too low, so I think it's more important to show LBS there is a life out there that doesn't include their MLCer.
If the MLCer ever does come out of it and decide to rejoin your world again, then great if you want it. But if they don't, then you should get to a point where that is just great too.
