My husband has a long history of mental ill health, I've always accepted him how he is and given him 100% support whilst holding firm boundaries and somehow we find our way through. But he's started to cross the boundaries. We have 2 kids and when well he's a great dad- the kids adore him. When he's not well he's intolerant, angry and sometimes violent (not directed at us, but in our presence). I know it's abusive, I know the effect it has on the kids and I, but how do you know when tearing the family apart is the lesser of 2 evils?
