For at least the past 2 years, you have dealt with rage/abuse/blame. No one in their right mind would expect you to be over it in 23 days of sobriety! Just because he's sober right now doesn't mean all is well and you just move on. There is alot of damage, and there are wounds to heal. He is sober, but still blaming the marriage etc for his drinking. That's bull. He drinks because he's an A, no other reason. Lots of "normies" have marital and personal struggles, they don't drink because of it. So don't get caught in his blame game. His drinking is his....only his.
So if I do the math.....23 days of sobriety with AA a couple of times a week and a counselor every other week. That means (and I'm guessing)....he's been to 6 or so meetings and has seen the counselor 1-2 times. GREAT that he's doing those things....but waaaaaay early in this process. Most A's are still in a real fog at this point and dealing with the withdrawal effects.
Tuffgirl is right. Put your oxygen mask on first. Find an AlAnon meeting with babysitting. There are also on line meetings. Read some of the suggested readings on here. "The Language of Letting Go" by Melody Beattie is a great daily read for a busy person. It helps to start your day out a little more centered. So is "Courage to Change" which is an AlAnon book.
Be gentle with yourself....
