Thanks so much for the insight from everyone. It is truly appreciated.
figgeroni: I like the analogy. In fact I have referred to the A as an addiction with her a long time ago when I would discuss it. It is an addiction, and he is her heroin. However, I'm not sure if she has the strength to do what is required to get to the point where I can be there for her. Time will tell. Thanks for your advice!
Peter2: I agree, written response is the way to go, as it gives her something to look at, and I can control what I say on paper, instead of mistakes in person, and most importantly, she will have the freedom to respond at her leisure did she even chooses to respond. Our W's may be similar. My W has a lot of resentment and blame, and compliance. I.e. She resents me be used she complied with what I wanted. We had several core issues that were decided like this. Unhealthy and incorrect.
I should be finished my draft tomorrow night, and I will put it up for analysis and editing from the forum then. Just got back from a night of hiking and playing hockey. Yes, I live in Canada! Feels great to GAL, just need to remember my Stop signs when I start thinking of W and OM.
