Welcome to SR, I hope you find the emotional support here that you need. You are so LUCKY that you made the right decision not to have sex with this guy. Once you are infected with Hep C, you may not discover you even have it until YEARS down the road and your liver is nothing but a sponge.
I know that part of your emotional distress is because you feel like you've been played the fool for this guy. YOu are not alone--I think everyone here has felt like that at one point. He is the one with the porblem, not you. You didnt' do anything wrong.
I hope you feel better soon!
