Pregnant and exposed—update

So a little over a month ago my so and me decided to invite a girl into the bedroom and have a threesome. We had an std talk and were suppose to be clean. Come to find out she got tested and has a sti. She won’t answer him with everything and I still have questions being that I am 32 weeks pregnant. Is it wrong if I reach out to her and try to talk some sense into her for answers? He might get mad over it but I’m just concerned for my unborn child.

DO NOT BASH OR JUDGE MY CHOICES

Update as of 6/21/2018

I was tested and everything came back negative THANK GOD for condoms. I did reach out to her but she refuses to speak to me. But that’s okay with me cuz I don’t have to worry about her anymore. Now just to focus on my unborn child.
