If there are no court orders then there is no restriction on your moving. You may want to consult with an attorney before leaving to determine if you should file for child support here in Ohio. Ultimately you will want to get your marriage terminated so that you can get married to your fiance. I am not sure of your timing but you may want to check with an attorney in Washington state to determine their residency requirements.
Unless their is an order stopping you from doing it you can move. I suggest getting everything in order by filing and getting divorced before moving. That saves you from him filing and beating you to court. Good luck.
