If it's only happened once in 15 years. Much worse happens to women on a daily basis. Worse in terms of name calling, shouting and other stuff has happened to me even.
I did slightly provoke him as well because i could see his anger was at boiling point but I didn't back down in my argument and get out of the room as he told me too.
Nothing has escalated since it happened and because it was so blatant I even brought it up (which I struggle to do with other stuff as he has a way of making it seem I'm the one in the wrong and overreacting) telling him it could never happen again. He even grudgingly apologised (which is massive as he is never sorry for anything) after I told him I wouldn't tolerate it.
Could it potentially be seen as a positive tipping point to promote positive behaviour changes?
