I lived with my ex-girlfriend for 6 years, from 2001-2007. I recently heard that she tested HIV positive in 2011. Obviously, I'm highly fearful of my status. However, I did have a comprehensive HIV/AIDS test as part of my US Green Card application in late 2002 - after we were sexually active for almost a year. Also, over the years, I've had various routine medical/health checks (though I'm not sure if they specifically included HIV tests). What are the chances that I am infected? To the best of my knowledge, we were monogamous during our relationship. I have always been (and still am) healthy, fit, high-energy... no symptoms of any kind whatsoever.
Any thoughts, advice?
