But nothing has really changed. He hasn't changed. The same things that were causing you pain are still there. So he has some feelings, doesn't change anything.
Now for you. Some good self-care is in order. If you really feel like you need professional help, then get it. Are there any al-anon or coda meetings in your area?
Are you working a recovery program for yourself? If so, then work YOUR program of recovery for yourself as hard as you WISH he'd work his.
I am really sorry that you are feeling this way. I understand it, I really do. I'm just a few months ahead of you on this process. And it is a process - where it's progress, not perfection. Just do the next right thing for you to shift your focus from him to you.
