[a little bit of this]

A girl (friend of mine) has been exposed to HIV multiple times her partner of many years finally took the turn for the worse and past a way a couple of years ago. She is now married but leading up to the marriage she was out sleeping around without protection and refuses to get tested, by the way she has hand pneumonia and 4 times in the last 4-6 months. While she was sleeping around she contracted an STD and gave it to her now husband without telling him she had been exposed until right before or shortly after the wedding. He didn't know until he had an outbreak. Well, I told her that she needs to take responsibility and take care of herself and get tested because these things as she knows can be put under reasonable control. She says "I know I probably have HIV" no big deal. I told her that its irresponsible beause even though she's married and he supposedly knows (i'm not sure if this is correct). I told her that even though she is married she could be positive
Isn't it irrepsonsible to the community at large to have been exposed multiple times, not get tested and sleep around without protection? Was I wrong by saying something?
I also told her it's not just about getting tested for everyone involved but to get tested for herself.
