Whats holding me here right now other than the fact I love this woman is the "hope" she is actually doing some soul searching and if she is grieving the OM and trying to process all of that and perhaps right now that's what's holding her back.
Coming home straight from the AP bed wasn't the plan but that's what happened and it could be that everything that she had wrapped up in that relationship is hitting her hard right now.
I know you've heard this before but it took years for her to get where she is. If she is going to come back, it will take awhile as well. Stay patient and judge her actions not words. That can be grueling, especially if it burns you to imagine her in bed with the OM. But if you do the DB principles -- GAL, do 180s, and stay detached and strong -- you'll either be ready for her when she returns or you'll be ready to move on with your new life.
