wish me luck

I've been talking to a guy lately that I really like. he takes relationships very seriously and has only been in 2 the last 6 years. we've been hanging out for about a month, multiple days a week, and last night he finally showed his interest in me by kissing me before he left my house. He really values honesty and communication. I think it's time to tell his about my HSV-2. I got it from my rapist. I've always practiced safe sex. Why am I so afraid he will judge me and not want anything to do with me anymore? I know herpes isn't a huge deal like it's been made out to be, I have all the facts, and I've never even had an outbreak. so why am I so scared?!
