This is a punt, to see whether it hits a nerve with others. No worries if it doesn't
By the time my last marriage finished, I'd developed such a reputation for being an alcoholic - and nasty with it - that I stopped drinking for 8 months. That's another story, documented elsewhere (I do call myself an alcoholic) - however, I only ranted whilst I was being abused.
Generally speaking, my personality doesn't change when I'm drunk. What was really happening was that I needed to be sober, to be able to override my justified feelings of loss & frustration. For the sake of the relationship, I controlled my natural responses to his control. After a few drinks, I "lost control" ... that is, I stopped helping my H to control me!!
Anyone living through this at the moment?
