Hi, I had to do the same with someone I had been seeing for a couple of months. I had my first outbreak and felt like I had to tell him straight away...the elephant in the room was a worse thought for me that just getting it out there. I asked him around and said I needed to talk to him...he knew something was wrong as soon as he arrived - I was still distraught from my diagnosis. He was amazing and there was no blame, he actually thought it was going to be something worse - H he could deal with! I couldn't deal with it so asked that we be just friends while I sort out all the emotional and physical stuff...and I had constant episodes for months and it was easier dealing with it outside of a relationship. He and I are still really good friends and he has so much respect for me. It's worth it to tell her and really, she needs to get tested too - you just may have contracted it from her. Being honest and sharing this is all about your integrity and if your intention is good no matter what happens you have been the best person you can be...and if she is the same she will see that and respond with love. If she doesn't then H may be a blessing down the track. Good luck :-)
