Touchy Subject

So I have some really good friends that are HIV+. I try and be supportive in the best way I know how, and honestly don’t really think about it much. I don’t believe that is something that should hinder a relationship of any sort. Sometimes I get really frustrated that some seem to allow the disease to take over their life and essentially give up. To one I got so upset I commented that it seems he was already dead. I know this wasn’t the best thing to say, and I don’t have it so I don’t know what it is to go through it, so I try and keep quiet and be a good friend.
But last night a guy I have been seeing for a short time told me that he was +. It was one of those things I never really thought would happen to me. He told me he understood if I wanted him to leave and never see him again. But that was out of the question. We’re not serious by any means, but we could be. That is how well we’ve been getting along. I am dating others too; I’m not at a point of committing to anyone. But despite how open minded I try and remain, what he told me will bear a strong weight in my mind. Am I evil or bad for thinking like that? This is new to me. I need some time to deliberate.
