Mariage Comtract Mistake

I caught my husband with other woman, cheating on me a year after we get married that's why i decides to file a annulment. But i was shocked when my attorny called and said that we aren't married. Yes! The wedding is real but theres mistake on mariage contract. Yes! I'm marries, but not to my cheater husband, but to a random guy, to a stranger. I don't know what to feel. I don't know if i will feel happy coz i'm not really my cheater husband or be angee coz i married to a stranger accidentaly because of a mariage contact mistake.
