Dang, I missed this post. one thing though: it is 0% your "fault". You probably already knew this, but it doesn't hurt to repeat it. The decision to drink again is always down to the addict. You have been an incredible support, but ultimately it's out of your hands.

Try to take care of you for a while, and do not be hard on yourself.

I hope DB finds his way back, but as long as he feels like he "misses out" while sober it will be a problem to stay that way. You can not just white knuckle it.

Truly hope he turns it around.
