Go get re checked when symptoms occur and still get a blood test no matter a what a doctor says and have protected sex always. Virul shedding can pass on herpes without symptoms so your boyfriend might not know if he has it.
Hey I can tell you be honest and tell your partner whats going on. Its the truth and you'll be free from it. Have protected sex from now on and go see your doctor again. There's a good chance you didn't pass it on and that's what your most worried about but honesty is key when not sure.
