FWIW I'm with Puppy (as usual). There is NO WAY on God's green earth I would even entertain the thought of giving full custody to someone who is engaging in irrational and potentially harmful activities...not with my kids. I would counter file for full custody and negotiate to 50/50. Maybe I'm just a skeptic or I am overly protective, but I would have a huge probelm with my kids being exposed to some stranger my S was cheating with. They are not thinking about the kids or what is in their best interest and certainly will not be doing their best "parenting" under these circumstances. Think long and hard about what you are and are not willing to live with, caving in to her demands will not win her back. You will just be stuck and regretting not standing up for you and your kids.
Just work on you and start GAL. You can't control her or change her actions, only she can. The fact that she is conflicted shows that she is not completely gone but you have to step up and be there for your kids and for yourself.
Has there been any exposure of her A with family or friends? Anyway to find out if OM is actually M?
