DII, sounds a lot like what I went through with my xah. He would be ok for a little while but would always relapse just when I started to let my guard down. He did a lot of drinking and driving. In February, he had a head-on collision with a mini-van carrying a family of four. He was drunk and crossed the center line. Thank God no one was killed but they were all injured. Now he is facing multiple felonies and a world of trouble. For me it was the ultimate wake-up call. I filed for divorce the next day and left him to deal with the consequences of his actions. Just a cautionary tale from my perspective. Best of luck with everything and my heart goes out to you. R.
