I dont think hes saying he wouldnt be hurt by the betrayal, he's saying since he wouldn't have gotten HIV, there were no lasting effects enough for it to be worth it to him to be upset over 15 years later. It's been over for a decade and a half.
Okay, that wasn't what I was getting from his post. I'm reading he would have gotten over it right away (which might be I have no idea how CEO works) just snap your fingers and everything is forgiven. I don't think everyone is really able to do that. However, CEO if you are able to do that then that's great.
