The weight of this situation because it’s a tangled mix of loyalty, morality, and friendship. Your friend clearly made a mistake in the past, but she’s devoted now. The tension arises because you know something her boyfriend doesn’t, and he’s planning a life-altering proposal under a false impression. From an ethical standpoint, transparency in relationships is crucial, especially when marriage is involved. While it’s ultimately your friend’s responsibility to confess, her withholding this information creates a fragile foundation built on omission, not trust. You’re in a tricky spot because stepping in could jeopardize your friendship, but staying silent puts you in a position of complicity.
The question you have to ask yourself is which matters more to you: preserving the friendship with your best friend or preventing a potentially devastating betrayal from reaching a point where it causes much more pain. If you choose to speak up, it must be done carefully and without revealing private details she hasn’t shared willingly. You could encourage her to confront the truth herself, framing it as an opportunity to enter marriage with a clean slate rather than risking being exposed later. Ultimately, honesty now, uncomfortable as it may be, is far kinder than allowing a major life decision to be made under false pretenses.
