He's not drinking...much?
How long do you think that will last?
I truly hope for himself and your children that he is working on himself and being a better person. You continue to work on you. Remember, it's behavior over the course of a VERY LONG TIME to prove if anyone can or will change.
You however have changed immensely. Our own flaws will always be a work in progress. Without being aware, it's so easy to slip back into that behavior. That won't happen to you because of all the work you have done. Be proud of who you are Butterfly.
Many hugs.
