I hate to say it, but it feels like false remorse to me, H4U. I could be wrong. My wife gave me the same thing, as soon as she got served and found out I was going for custody of OUR boys. Then suddenly it was all crocodile tears and promising to do ANYTHING.
Still, you have to call her bluff. Lay out your terms (and yours sound very good), and have a good transparency and intel system in place to see if she's following it.
I've posted before that there are several layers of remorse. There's the "I'm sorry I got caught," and the "I"m sorry my affair is over" and even the "I'm sorry I hurt you." But you will know when you truly get the "I'm sorry I caused you and our family this pain, and I'm also sorry that I've failed to live up to my own sense of morals and character."
This just doesn't smell like that to me. Again, I could be wrong.
