I had sex with someone who had sex with a hiv ...

Good afternoon, please, I'd like some information. I had sex with a person who had sex with an HIV carrier (his ex-husband), but luckily he did not get it. It's been 10 years and she does regular testing, there's nothing. Still, am I at risk of contracting the disease? Thank you very much
Expert answer:

You will only get HIV if you have sex without a condom with someone who has HIV.
