“I didn’t tell her I’m HIV-positive”

I’m 27 years old, male, and HIV-positive. I met a girl and slept with her several times without telling her about the HIV. We used condoms every time, and I am on medication and undetectable.

I know it was the wrong thing to do, not talking about it. Now I am worried if I tell her, in an attempt to come clean and potentially continue a relationship, she could also send me to jail.

What should I do?
