Sorry to hear your predicament. I don't really have any advice for you either. My H's OW was a complete secret the whole time so I never had to deal with what you and nikkib are going thru.
I believe the main thing is to realize what you want your boundaries to be and stick to them. Continue to GAL big time, and don't let her be the one in control of your happiness. Of course that's the hardest thing to do, but we need to realize that it is problably one of the reasons we are here today. That we let them be the reason for our hapiness.
I wish you well, and you just think about all the other things that God has done in your life that you can be thankful for. For myself, no matter how bad it was and how much it hurt me, I do thank the Lord for allowing me to go thru such an evil and horrible trial, because it has caused me to become the person I am becoming today and it would not have happened otherwise. Remember, you still can have hope. My R is an example, my H is back with me after wanting to leave me for another woman and that he never loved me to begin with, but now he wants me to be his wife forever. And it can happen to you too.
My soul goes out to you,
