That aside, you tell your husband the truth.
I live en México and the whole and official name of the country is Estados Unidos Mexicanos something like United States of Mexico or Mexican United States , but only in few ocassions we use it that form as we prefer to name it only Mexico.
You may kick it down the road, but the truth will come out and you will pay a higher premium on your sin.
You have to really want your husband and you have to be honest with yourself.
