"Wife, counseling is a very personal thing, I'm dealing with personal issues, faults, weaknesses and questions about my life that I've never dealt with before. This is all very new to me and I prefer to keep the details of my counseling to myself for the time being. I wasn't ignoring your emails, I had a very busy day today and I would prefer that if you have to ask me questions like this, don't do it over email, text, phone or voicemail, do it in person, face to face which is a more personal way of communicating with someone. I appreciate you understanding this."
No details, just gloss over the high points without giving her the high def picture of everything you're discussing in counseling. She is specific with things like AA, anger management, lying, those are all issues she has with you and although they're all important those are things she may need to see a counselor about and learn to let you take care of you.
No more emails concerning your counseling, plans on what you're doing, etc. You can text/email stuff like, "how are the kids?" "picking up the kids after school" "taking the kids out for supper"
