W less angry with me, but not ready for piecing

[not an ex yet]

As a woman I can guarantee you that your W is thinking about what she has done every time she speaks to you. I would bet that at some point when the R is more stable, if not now, she will want to apologize and talk about what happened. The problem is timing. I know I have a hard time wanting to bring something like that up when things are going so well. It's like you don't want to screw up everyone's happy times with something like that. For me, (keep in mind I have never had an A, so I could be way off) I would almost need my H to break the ice and bring it up in order to open the door for an apology.

Maybe you should decide if you REALLY do forgive your wife, and when you are sure you have forgiven her...tell her. That would be the perfect opportunity for her to let out her feelings on it.
Maybe at some point she will approach you about it, but either way I think you need to be sure you have forgiven her. Once you do, maybe the need for you to get an apology or explanation from her won't be so important.
Just my 2 cents.
