Been there, done that.....and I made a lot of mistakes being nice and accomodating to my ex-husband. I too am unemployed and recently divorced this year. We filed no-contest with no attorneys in court with us, although I did pay an attorney to look over our divorce agreement before I signed anything to be filed with the court.
If your name is on the house then you have every right to be there and your husband cannot force you out until the divorce is final, provided that you do not want the house. I am not sure what the laws are if you are renting, but if the lease is in your name too and he is paying the rent, then I do believe you can still stay there.
If you have your name on any bank accounts with your husband you are entitled to half of what is in the accounts, so I would make those withdrawals now and open accounts in just your name. He may have already drained those bank accounts and moved the money into just his name....this happened to me.
You need time to get some things in order and make living arrangements for yourself. Is there a friend or relative you can stay with for a time until you can get on your feet, either now or after the divorce goes through? If you can put off moving out until the divorce is final I would do that, as long as you are not in any danger in your husband's presence.
If he wants the divorce perhaps your husband should move out until everything is done in court. That is what my ex-husband did so I could get my things together. Plus he could not emotionally handle living with me anymore even though he wanted the divorce and I did not.
As for your emotions going wild, I engaged in bickering with my ex-husband quite often during the process of divorcing, which was really strange because we did not argue often during our marriage. The strain of what was happening did take it's toll on me, and I did things I normally would not do. I agree that professional counseling would help you deal with the situation, and minimizing communication with your husband may help as well.
I feel for you because I know this situation is not easy to deal with. In time it will get better, but it is very stressful to be in your place right now. Try to take care of yourself the best you can. Eat as healthy as you can and get adequate rest.
