it's a possibility he gave it to you. this disease is like having a ringworm...if he has it on his lips and touch your private area...then he infected you.
i know so many people who have this and all of them do the same thing. they dont tell there sex partner they have it b/c it's really hard to talk about it. and they think if they dont get any symptoms they dont have to worry about infecting their partner.
i have 1&2 i really believe my son's father gave it to me. he also gave it to his g/f after me w/o telling her. when i first told him he didnt even seem surprised, as if he knew.
i had a girlfriend that was engaged and she told me if her finance ever found out, she's going to pretend to be surprised.
1 out of every 6 people have this. i had it for 13 years and it took me years to get over it. i hardly every have outbreaks, but in the begining i would get them a lot due to stress.
if you and your b/f ever break up i was told they have internet dating site with people who have hsv.
good luck
