Not at all. I pretty much expect to be asked again. Let me explain.
But first, this actually brings up another rom-com trope-- asking out someone who actively hates you, or for whom you have expressed animosity. People just don’t do that in real life.
I have never rejected a man (or woman, for that matter) with a zinger like “Not if we were the only two uninfected after the zombie apocalypse,” because no one I felt that way about has ever asked me out.
Well, I once was being pursued (semi-stalked) by a guy who really and truly did have brain damage (serious closed-head injury about 10 years earlier). He wouldn’t have gotten a zinger, though. I went to the agency that helped him live independently (he was nearly independent, but had a caseworker check in on him six times a year, and he had an emergency number he could call), and got a meeting with me, his caseworker, and his caseworker’s supervisor where I told him to leave me alone, and it was not negotiable.
Anyway, save for that one instance, I have never had to tell a guy off. Very few people have attempted to pick me up, and I have been fortunate enough that not giving the men (it was always men) any information has kept them out of my life.
Everyone else has been a friend wanting to go a little further. I legitimately did not want to hurt their feelings. I gave the “I can’t, I’m busy,” and hoped the second ask was also for a specific event, and not an open invitation.
However, I remember one guy very specifically whom I hadn’t known long, when I happened to be in the middle of some personal crap, and had no room for a relationship. I knew him from campus Hillel, and we shared a bentsher one evening. He stopped by my door later to ask me out. His second ask was open-ended.
I said something like "I’m so busy with school right now-- I’d have to look at my calendar and call you-- and honestly, right now, it looks like a page of Talmud. But I’ll see you next Shabbes at Hillel. I always sit with Julie and Mike.
That response was crafted on the spot as best I could to communicate “I don’t want to go out with you, but I value your friendship.”
He was there the next week, and sat with us.
