Your T may be waiting for you to bring it up. I know my T wouldn't bring up really hard topics like that. Instead she would wait for me to bring them up. Assuming that if I'm not ready to talk about it I wont bring it up. If you are not comfortable bringing it up for talking about, you could bring up that you haven't been talking about it to see if your T is not willing to bring it up unless you do. Good luck.
