His drinking pattern is abnormal, and excessive. Alot of A's are good at intermittent control, it doesn't last. It's affecting your relationship. You want to give him a chance to "see this issue" and a chance "to address it". There is nothing you can do to make that happen, and it's not your responsibility. You will make yourself crazy trying to figure this stuff out, nothing the A does makes sense. Be glad you don't have children in the picture. I agree that you would benefit from AlAnon...you can work on your own recovery from this.
