I wanted to give an update here.
Thanks for sharing your thoughts, everyone! I really considered my feelings - my guilt comes from that he asked me a direct question and I didn’t answer. I felt like crying all day about the not being direct, so I called my GP.
My doctor’s advice was actually in direct opposition to what you all suggested, though I truly understand your perspective. She thinks the odds are so incredibly low of that encounter that there’s no need to be putting this much pressure on myself. Quite surprisingly, she basically said if he really cares about this virus he shouldn’t be asking after the fact, and that it takes two to tango. It was a surprising take from a GP, but I’m weighing everyone’s thoughts here.
I’m not quite sure I agree with her, but she gave me a lot of interesting perspective. @mr_hopp thanks so much for taking the time to share these things but as this is a one-off encounter and it probably isn’t moving forward, we’re talking about a situation where I will probably never trust this person or need to because I won’t be talking to him again. I could be unnecessarily freaking someone out for 2 months or more - someone I don’t even know if Im safe to tell. What if he’s a vindictive person? What if he’s violent? It’s a lot to consider.
