I would suggest talking with someone to help you organize your thoughts and plans. A counselor, maybe or a divorce attorney if that is your plan.
I think you need to calm down and make a plan. Don't take any hasty actions that may hurt you in the long run. For example, before I filed for divorce my attorney advised me not to leave the marital home (I was planning to move to my sister's house until the divorce was finalized.)
Find out what you need to do to protect yourself, your rights and secure your assets. Don't show your hand until you have your stuff in order. If he is lying and hiding things, you don't want to give him a chance to mess with your finances for example. Meet with an attorney and go from there.
