No worries about hiv for you, because there haven't been any new scientific papers out disagreeing with what you were told on March 3. I'm not sure why you are asking the same question today but the good thing about your situation is that hiv research is 40 years old and hiv prevention is straightforward, so don't expect the advice here to change. If you continue to find it makes you too anxious thinking what-ifs about your encounter, you can take a duo test after 4 weeks for a conclusive result.
At this point in time, I would avoid encounters with people you don't live with because of the likely 100% risk to you contracting or spreading Covid (if one of you was positive) in which case you might also spread it to your loved ones.
Since neither of you were social distancing, I hope you check out this forum for information on why you should be today. https://www.medhelp.org/forums/Coronavirus/show/2203
Your health is your wealth, so I hope you remain healthy to be able to enjoy life. Many infected Covid patients including young people are under the misunderstanding that they have zero risk from Covid, but will discover that not all of them will be spared permanent lung and related heart issues in which case they have lost that wealth.
