Is it right to be disgusted?

I was dating this guy for a long, long time. I actuallly fell for him. We waited forever to do anything “sexual” because we both wanted to go slow and do things right before jumping into anything. One night things got a little hot and heavy and he said he needed to talk to me. To make a long story short, he told me before we did anything that he had herpes and had gotten it from a girl he dated for a year that had cheated on him several times. He says he never gets outbreaks and his life is completely normal and that if we had sex that i’d eventually get it. I really don’t know what to think right now. A part of me is disgusted and does not want to be with him now. And the other part of me knows how much i care about him. I guess i would think differently if i was in the other person’s shoes so i know i shouldn’t judge him. What do you think?
