Hey pcjohnson61, I am too in a WAW sitch. It is tough, really tough. It is helping me to know many overcame this difficulties and I find that DR is giving me hope, that it is what I need.
This is what I noticed gave some results.
You have to be your best in front of W, I started caring more about my aspect, look lovingly but independent, relaxed, if you can use humor and be a pleasant person to be around - show that you want to give her all the space she needs - if you have to fight try not to get enraged and storm (this is very hard for me) - speak with a soft voice - don't look in panic - be there but not too much - and most important of all look what it works and do MORE of it and look what it DOESN'T work and do LESS of it.
For example, I tried to be cold and detached with my W and she got even more cold and detached, I understood she thought I don't care and so that she is right to walk away - in my sitch the optimum is on a very fine line - I have to show I care without pursuing her, and I'm still not sure how to do it. Few days ago we where joking on the fact that also if our lives are going to take separate paths would be nice to live together our "silver years" in the same retirement home. I pushed a bit and said hey maybe in 5 years - but she backed up fast and said "I was thinking more in 20 years". It is like with a wild animal you have to get close very slowly, any sudden move and she runs away very fast.
