This is hard to answer because I have no idea what makes the social security office think you are married. You said you took a blood test so perhaps you did obtain a marriage license. You may need to see if you can provide an affidavit or some other type of statement explaining that you did not, in fact, marry the other person. This assumes you did not actually marry the other person.
