If the marriage was consummated, no. Annulment is not a legal definition in most states. The church can issue an annulment, but the state will require a divorce. Marriage is a serious step and cannot just be undone for whatever reason, not only is it a legal document, but it is a moral commitment to another person that needs to be done with the greatest of care and respect. I would examine why your "ex" is confiding in you now that he is a legally married man. I would get as far away from the situation as I can as fast as you can, it will only cause you more heartache and trouble. Leave the ex's and the past where they belong, forgotten.
