I wish I knew what you know about alcohol after 2 years together. I wasted 34 years of my life thinking I could handle anything with my axh. WRONG!! They always win and you lose. If it was me, I would run and run fast and not look back. Life with an addict/alcoholic is lonely and painful. I wouldn't wish this on my worst enemy.
Sending hugs that you take care of you, and give him to God to watch over. Its a bigger job then you can handle.
