Ajay, trying to mind read the WAS will drive you nuts... you have to stop analyzing everything they say and do. I know how hard this is, and I still try to fight the urge myself.
You'll hear a lot of great advice about shifting the focus from them back to you here. I saw someone post this here somewhere and I'll try to paraphrase as best as I can. You have to make real changes for yourself for DBing to work- if you only do it to save your marriage it'll never work, and the WAS see right through it.
Mr Bond gave you great advice- avoid her right now. Focus on what you need to do for YOU. It'll keep you sane.
