To tell my bro his wife is secretly preventing pregnancy?

[MyameVyce]

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?

Well my vote went the wrong way. you really screwed it by asking the question twice, different ways around.

AIBU "To tell my bro"

AIBU "to keep this info to myself?"

🙄

Yes but he should also have a choice no?? If she doesn’t want kids that’s ok, but he does and he should have the choice to leave and find someone who does want the same things.

You tell him because if he ever finds out you didn’t your relationship is ruined. Keeping secrets from siblings ends badly. If my best friend told me this about her husband I would keep my lips shut. As I wouldn’t want to be in there marriage issues. However a sibling affect your whole family. Tell your bro and asap your best friend is right!

yup its not the choice to have kids or not, its the lie.

People are not always logical or sensible and the OP suggests that SIL has a history of creating drama. She may well have said this to get attention even though not true. If SIL is what is often termed a 'drama llama', the most unbelievable part of this story would be that she could keep this up for two years without blabbing to someone or making a fuss in some way.

It is, but it's not her choice alone. If she is actively 'trying' for a baby and is still on birth control, it's a way of manipulating the relationship to retain her husband.

For two years, she's been lying to her husband. If she genuinely doesn't want kids and knows this could be a deal breaker in their marriage, what's her endgame plan here, hoping he'll stop asking questions, not want to go down testing options, IVF, etc.

Yes, it's her body, her choice, but she's also chosen to try for a baby while still on birth control. Would you say the same if a man removed a condom, didn't tell his partner and said it's my body, my choice?

Have a little grow up.
