Your question was fully answered that you were neither at risk nor did you put anyone at risk (nor could you ever) from hugging them.

I agree that this is not a risk. The only risks for HIV are unprotected vaginal or anal sex or sharing IV drug needles. A hug would not transmit anything. However, if you had unprotected sex with someone you are unsure of their status, then you yourself risked HIV. Is that what happened?
I don't think you should post in portuguese. Luckily for you, I'm brazilian! You don't have to worry about this episode, as HIV dies quickly when exposed to air.
