sbat, your wife chose to marry an alcoholic, and instead, she now has a healthy loving normal man. That's not what she wanted, and not what she chose.
She chose to marry a man she could belittle, and feel superior to, and blame her unhappiness on. *slips on a banana peel* That's gone now, and she's had to resort to belittling you for past sins from many years ago - it's all she has left to beat you up with.
Until she recognizes this pattern and has a miraculous change - and decides that she in fact wants a healthy man and not one she can feel good about wounding all the time, this won't change.
Best wishes. Congratulations on your sobriety and positive life changes. I'm sorry your wife isn't enjoying it.
I don't think that it's meanness or codependency; it's unhappiness.
It sounds like your wife is harboring anger and resentment because she hasn't forgiven you for your past transgressions. And, she may never get over the feelings of bitterness and loss that I'm sure she must be feeling. After all, you were an addict for the better part of 20 years. That's a lot of heartache and disappointment... for both of you. Berating you is her way of venting her frustration. But, you're right... it is verbal abuse. You need to have a long sit down talk with her... and let her know that while you realize that your addiction caused her grief and suffering; her hostile and disparaging remarks are aggravating and demoralizing. Explain to her that you are sorry and are trying to make amends. But, that words of support will carry you further in your recovery efforts; than bitter and sad reminders of the past.
