Hi MEA, Well, he is not suffering from a mental illnes but seems a reactive disorder, low mood and over anxiety,with acting out and self harm behaviour in a histrionic manner. For the first time perhaps in his life he is being forced to face up to and live with the consequences of his selfish and malicious behaviour.
I wish I could say he will not do himself a nasty, but tho most of it is attention seeking , he could just get himself into a frenzied enuff state, booze etc, to do real harm to himself.But that is his decision, he is not psychotic, he is aware of what he is doing.
One thing is certain, he is not your responsibilty now, let his loving family cope and the Docs.
Rewarding him with your care and attention will only make him do more of the same.The focus is as ever on him, not you or his daughter, who have both suffered so much..
They did not keep him in Hospital as he is not ill, just letting himself go demanding attention,acting out, and trying to force your hand, and as you say emotional blackmail carried to the ultimate. It may let him learn to make the coping and growth we have had,but I doubt it. Good for you for being so strong and clear and kind too.
But stay away as you have done or he will slowly pull you back in again.
This is not any more than him again trying to take control. So do not go round again, or let him in.
I think.. phone his family or Doc if he sounds at risk.
Do not make yourself responsible for his behaviour.
Change phone numbers if need be. Others can help, not your job now.
I believe he is not legally to annoy or harass you, didn't you have an interdict?.. Does that not still stand? Anyway get back and let us know how you are!
