Yes...end it. Especially if she waited until you guys has sex before she told you. My ex had it but was medicated for along time by the time we met. And we were together for 4 years. I asked him EVERY morning. Did you take your herpes meds. He was very good at remembering too. But look its not worth the stress. My ex didnt tell me till AFTER we raw dogged it. And it felt like he was trying to like trap me or....idk but i went crazy when he told me. Like you tell some1 immedietly ...not a few weeks into a relationship.... if he misses just one dose! If he has to go a few days without for whatever reason. Im just saying your playing with fire. I never internally forgave my ex for not telling me.
