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?

You really don’t seem to get how incredibly wrong this is. You need to tell her so she knows what is going on. You have created what is a really serious situation and you need to come clean. If it should lead to legal issues then I’m afraid that is something you need to take ownership of. You did something very serious here and if you truly want to do the right thing, do it and take the consequences whatever they may be.
It will be worse for you if she finds out the hard way legally, because you knowingly slept with her without warning her. Condoms are NOT, I repeat, NOT a 100% fool proof method. Why do you think so many oops pregnancies happen on them? You might have given this girl a std that may or may not kill her, because you got horny. What a present.
