Be very careful telling others about your sitch. Your wife needs as smooth a path back to MR2.0 with you as possible. Telling your family is just another obstacle to her coming back. I know in my sitch if I had told friends and family about my wife wanting a D, and and any of the details of her EA I'm pretty sure it's be divorced today. I'm sure that's not the case for everyone, but my wife is not one to face people she's disappointed.
Detachment is but forgetting. It's not putting the person out of sight and/or mind. It is being happy and content with yourself. It is not reacting emotionally to what she says it does. Google "self-differentiation in marriage". It is a complex thing so don't beat yourself up for but getting it, we all struggled with it as a concept.
Have in there, it does get better one way or another.
