"if you knew my secret, you wouldn't want me."
That couldn't be farther from the truth. I know it's hard to just find out, but promise me when I tell you, you will find someone again (or get back with your ex, etc). Here's the thing -- when you disclose something like this to someone, it says a ton about you. It shows not only that you care about THEM, but that you are an honest person with integrity and character. Those are two values that can be extremely hard to find in people.
So if it's the right guy, he will be accepting of you, and hopefully, even supportive. I'm a guy, but the girl I'm seeing now, when I told her, obviously she was surprised at first but she grabbed me and pulled me in for a hug and thanked me for telling her. She asked some questions, did her own research, Etc, but were still together and we are crazy about each other. She SUPPORTS me. I think honestly me having herpes and telling her about it made us grow as a couple and we became so much closer. After telling someone about it, I feel like I can tell that person anything.
So sorry for rambling a bit there, but the point is, you're not unwanted. The right person will accept it and be there for you. Good luck!
