This is just my two cents, for those dealing with anger and needing to detach..
It is hard, having known your spouse and quite possibly the issues they faced in their past that is contributing to or causing the MLC, to want to let go of them.
The reality is though, in the course of the MLC, they have one foot in and one foot out of the marriage. If you had just met this person, would you let them treat you the way they do? Of course not. You too need to have one foot in and foot out and you need to put more weight on the latter.
Use that anger and all of that hurt and channel it through faith, faith in yourself, God, your friends, your family, that you will get through this with their help, and live like they aren't coming back. If they don't make amends, do you want them back? No, so start building that life now. If they can fix themselves, they can come with. If not, who needs 'em at that point?
The scariest thing is facing the unknown and having to rebuild. The only thing that helps make the unfamiliar familiar is time and that's something we keep saying here over and over.
Just keep in mind they did things to you that you wouldn't accept in a total stranger. Yes be ready to forgive one day, but also be ready to walk away from them like you would that stranger.
That's the key to GAL.
