I think one thing you have to remember is that you should not believe anything you hear...and half of what you see as said by many on here. A WAS will lie to themselves as much as they do you. You've absolutely need to detach. No only to DB, but also for yor own health. They have to see you getting yourself together and getting a life apart from them...moving on if you will.
Trust me, they notice everything. With my XW, I would make a change it would be months before she would mention it. But she did notice and I planted a seed of doubt. Time is your ally!
