I live in the state and Washington and was wondering if I have a case for defamation? I have an ex-girlfriend who saw me with a female friend in public. I don't know what she was thinking but she is now trying to sue me for transmitting HSV-2 to her. Unfortunately for her I don't have HSV-2 and have test results to prove it. Because of her reckless actions I was publicly humiliated and some of my peers have dissociated themselves from me. But most importantly my female friend wasn't any drama dealing with my ex-girlfriend. Do I have a case?
