From what I can gather you don't want a divorce, the advice on this board will be VERY different to what other boards advise and I would strongly suggest you stick with one approach as much as possible otherwise your going to be all over the place.
I agree with this. You need to choose an approach. Part of the DR book tells you to experiment and monitor the results. How do you know what is working if you are combining approaches?
I don't think you should completely ignore your W while you are both in the same house. You should GAL and do your own thing, but you should also be civil. Have you read about the friendly neighbor-type approach described in some of the other threads here?
