About 2 years ago my bro told me he’s trying for a baby with his wife. He was really excited and was hoping it would happen quickly for them because he can’t wait to be a dad. With it being a personal sensitive topic I would not ask further updates, but he’s made a few rueful comments about how it isn’t happening. He mentioned that his wife had said she doesn’t want fertility investigations or treatments and if it doesn’t happen naturally she’d be ok with that.
Problem is that SIL made a weird kind of confession to me where she basically told me she’s on contraception and my bro doesn’t know. Conversation was bizarre. She giggled and saying “ssshhhh” don’t tell him.
I have no interest in getting involved in someone else’s marital problems but I told my best friend about this and she strongly thought I needed to tell my bro.
AIBU to keep this info to myself?
