My boyfriend and I have been together for 2 years, about a month ago I had my first genital outbreak . I immediately accused him of cheating to which he swears on everything he's never cheated on me . He offered to find a place to have a lie detector test done and the whole nine yards .. after doing a ton of research I learned all the facts- it can live dormant in your body and yada yada .. so we both get blood tested and I get swabbed - the swab confirmed that it's hsv 1 .. my blood work came back negative so I was told this is something new to my body and hasn't been living dormant .. my boyfriend and I just assumed he was the carrier and that his bloodwork should show up as positive, (after alot of thought he recalls having cold sore like things on his lips a few times when he was younger but never thought it was herpes) .. His blood work came back completely negative . They told us he had no history of antibodies whatsoever .. my question is : could our blood work be wrong ? Or is it 100% he slept with someone else and gave it to me .. he's being very supportive and promises he's hasn't touched another person since we met .. it's really breaking my heart not to believe him since we have a happy and healthy relationship and I never ever suspected him of being unfaithful until now .. please help .
