I remember 9 months ago going to my first Al-Anon meeting mad as hell because everyone kept telling me I needed to work on myself. I thought "why? I am not the alcoholic!" It took a few months of meetings and a good therapist and lots of reading to come to the conclusion that most definitely I am part of this problem and I can do a lot of things to be a part of the solution or to make a bigger mess of it all.
Replace "9 months" with "5 years" and I can ditto that statement.
Four weeks is a very short time.
My X was sober for 5 months. And then hit an even deeper bottom than before. Because he chose to think himself strong and abandon the support that had been, and still was, available to him.
But I still had my support. So while he's falling, I'm standing.
I'm not saying that to scare you. I'm saying it to remind you that
you are a separate person, and
you can live a rich, happy life whether or not your A is actively drinking. But to get there, you need to figure out how you got here.
Big hugs.
