GH, you have to make sure the EA/PA is done, through transparency and verification. Everything else will be wasted otherwise.
One thing I've found is that bringing up relationship talks with my W is very hard, and almost always (99.999999999%) of the time counterproductive. We talk about it with our MC, but that's a controlled situation.
If she brings up your R, listen. Pay attention as if your life depended on it. Validate what she says without trying to justify or explain your side. Just listen. If you're not sure how to answer something when she asks you a tough question, simply say "I'm not sure how I feel about that right now, I"ll have to think about it."
