Chel, I am sorry I didn't see this sooner and I do not have a lot of time right this moment for all the niceties of communication. Your husband was being nice to you so that things would go his way, it was his best shot. You are seeing now the reality of how he will behave. My advice is under no circumstances should you go through a divorce without your own legal counsel. You cannot trust this person, you cannot predict that he will think what the law actually says you deserve is fair! You don't have to tell him all this. All you have to do is retain your own lawyer and tell him it's for the best for everyone, tell him it's in his best interest as well and leave it at that.
I don't think you should move out unless your attorney recommends it--there may be long term implications until you have a property settlement agreement in place and trust me that could take a while. I my case I was able to leave because we had two homes and there were no implications for me.
I will try to get back here later this evening but in the meantime I hope I have given you some information that is helpful. You are talking about financial impact here that will last the rest of your life. I wouldn't put that future in the hands of someone who has betrayed you so much already. Stay strong. Wonder
