I am so sorry you are going through this. I was in a similar situation about two months ago, although my AH did not leave; when I wish he would’ve in order to give me the space I need to process all of this.
Unfortunately very early sobriety is definitely a time that they need to focus on themselves. At this time, I recommend focusing on you and the children. Good for you on going to al anon! The al anon group has helped many people! I have been going myself for the last couple of months as well and it helps put your focus where it needs to be...on you and what you want rather than on your AH.
There is a wealth of knowledge on this site as well on alcoholism and the more you know about this disease the better.
My AH is sober 2 months but is cold as a cucumber while at the same time professing his love for me.
There are very big changes ahead and the best you can do is continue to do what YOU need to do; not react to his actions. There is NOTHING about alcoholism that is fair.
Keep posting to this site. There are very caring people on here to help!
Good luck at your meeting and let us know how it goes.
Peace to you!
