Hi Serinityprayer,
Its just a thought on my part and my experience of these out -burst, My XAH used to do that, usually it was because, that he'd been planning it ! to leave at or over a minor disagreement,or he caused one,so he could get back to his drinking,
When he was in Recovery for a while ,he told me that he did it on purpose and had an argument planned to start with me,of course I didnt realize this,in the end I had to let go! and let God ,the addiction was too much for him.
All my best wishes to you,its such a baffling disease
