Dissed by disease

I am on a online dating website.
Overall, the men I have talked to or met are decent.
Contact normally starts with an email, then we IM, and then if the connection is still there, we talk on the phone and then go on a date.

Last night, I was on and a guy asked me if I wanted to talk via IM. "Sure." I said.
That's when the question, after question, after question came at me. Let me say, I am okay with questions...but not when they make me feel like I am on a job interview. I basically was not given a chance to ask in return. When I tried to throw a little humor out there, it was ignored and the questions continued.

When I finally answered all of his questions to his satisfaction, he said, "Okay, we can talk... but I have to tell you that I have genital herpes."

WHOA! Hold up! NOT something I am interested in at all!!! So what's the correct response to that???

me: "Thanks for being honest."
him:"So that means we are still going to talk?"
me: "Well, just because I am IMing you doesn't mean I am going to sleep with you."
him: "Where do you live again?"
me:"B-town"
him: "Oh. that's too far of a drive. nice talking to you. bye."

What???!!!! Wait a minute. You have a disease and you diss me because of distance??

Oh wait, no... it is because I won't share in your disease. Somehow... I still feel dissed.
