I posted a thread last night which I will post in a comment after this OP.
Things have only got worse (sincee last night) and today DH has lost it. He has made up lots of things and accused me of lots of things in the last 24 hours that are just not true. I feel that he is losing his mind. He is extremely angry with me and I just can't stop the torrent of anger over email and text.
I am 35 weeks pregnant and have not done anything apart from the usual: sleep and eat, in the last 24 hours. But he is accusing me of defying him and deceiving him.
I cannot stop the accusations. He doesn't want me in the house with him but he doesn't want me to leave the house either. If I argue back it makes him worse. If I go silent, he accuses me of ignoring him/being negligent. He is out of the house at the moment and I am frozen about whether to leave or not. He keeps sending me warnings like: "I would advise you to think very carefully about how you will treat me when I return." There is no actual explanation about what the problem is.
He is in the frame of mind where he cannot see anything other than from an incredibly vigilant, controlling, self-destructive mindset where I have done him wrong. I have told him that I am worried for his mental health and he says that I am the one who is mentally ill.
You'll see from the thread above he is difficult to live with due to his bipolar, but it has never been as bad as it has been in the last 24 hours.
I feel that if I leave the house, he will have more reason to feel that I am being deceptive/defiant and he will feel inside that it just goes to show how I am set on hurting him and that I am in the wrong. Whereas if I stay, he will insist i accept reality as he defines it (in his current mental state) which is that I am torturing him and lying to him and deceiving him and I need to change. This feels like emperor's new clothes.
What should I do?
Should I go to a friend's house, tell him where I am and get a witness to the behaviour? Or should I check into a hotel? Or should I stay put and weather the storm with him and when he has calmed down, try to talk to him rationally?
