@mm7677 this is an old question, you may want to start a new question for your situation.
In general, if you have a common law marriage in a state that recognizes common law marriages, that marriage will be recognized if you move to another state. That means you are married and can file as married. On the other hand, if you don't want to be married, you will need a full legal divorce. Common law marriage is not something that can be switched on and off at your convenience like a light switch.
