Ajm, just read the last 8-9 pages of this thread. I am at work, cant get into details, just wanted to say to you that you NEED to stay "stable", solid, and strong. I know it is hard time for you but no matter what happens with your W moving out, with your kids knowing what's gonna happen, you need to stay strong. When you set boundaries, guard them, just like you did with the lawyer, when you want something to be clear with her, DO it, dont be afraid of her reactions.
She is lost. Confused, tired, feeling guilt for wanting and needing to leave but at the same time something or someone is pulling her away. I know that the seperation may look scary but in fact it could bring peace in her mind and help your R get thru this faster. I wish I had kicked my H out months before he actually left. I believe the damage done during those months is what cant be repaired now(it also made his affair more fun with all the secrecy etc and made it last more that it would...)
You know the rubberband effect? She can pull away all she wants, if she knows you are there, she will come back to you. Will you be there? That's something else...
Have you read "The way of the superior man" by D. Deida? I think it is a good read for you now. Ohh well, I am in a hurry, I hope I make sense, next time I will post to you in Greek... K
