The main marker to look at to determine if someone is infected is: HBsAg (Hep B Surface Antigen)
The first set of results (your boyfriends?) show that he does have HBV.
The second set of results (yours) show that you do not have HBV at this time. It looks like you have had it at some point in your life and your body has cleared it on its own ….so you should now be immune. Did they test you for HBsAb (Hep B surface antibodies)? The clinic probably wants you to return to test your for antibodies to confirm that you are immune. 95% of people infected as an adult will clear the virus on their own.
Please refer to Hep B welcome page for some more detailed information that should be helpful:
