I'm sorry that you are having a rough time right now. Just try to remember that they all say the same things from time to time. Just a few hours before things seemed to be going fine. Are you sure this won't just blow over in a day or two? What did he say when you said you were not in agreement?
The fact is that he has not filed for a divorce, has not talked to a lawyer, and is not wanting to upset you by doing something that you do not agree with.
You have a long ways to go if this is going to work but you have to stop acting like it is the end of the world everytime he says negative things about the marriage. Try to take it in stride.
Try to get some sleep and then I would pack up your stuff and head to your friends house and stay there for a few days and let him be in his cave for awhile.
