Yes - sobriety is just the first step, for everyone. Then the WORK starts, on both sides.
It isn't easy Dad - 5 months in the face of years of chaos is like drops in a bucket. And YOU didn't get 2 months away to focus on your side of the street - you continued to try to fit it in around the rest of the responsibilities & obligations that you can't take a break from.... kids, jobs, mortgages, whatever. Early Recovery is not equal on all sides.
At 5 months, I was still holding my breath for a relapse, if I'm being honest. I needed to see new, healthier patterns repeated again & again & again before they would start to feel "normal". I was still identifying my "hurts". Hang in there.
