My brothers girlfriend told me some really personal stuff, and I don’t know if I can talk to him about it. The girlfriend, let’s call her A, and I are really close like we stay up talking and stuff. One night, we delve into some really personal shit, like how she had a miscarriage at 15. And I’m super close with my brother, and he knows all of this, but he doesn’t know that I know. I have no idea if I should talk to him about it or not.
