You have been with your partner for a decade so I understand that you are concerned for his well-being. Do you think substance abuse might be causing this behaviour? Whatever the case is, you cannot help him as long as you are in this situation. Can you push a car while you are inside it? I agree with the other responders. The first thing you need to do is to get out of that house and back with your family, or with people who can support you. Only then can you consider helping him out. From the outside. Please be safe.
