I just lied to BFF about TTC. I tell her almost everything (like... too much...) and it's already hard to keep the secret.

I confided a few details about my PCOS/endo/whatever symptoms and my fertility fears a few years ago... then after a few drinks she started blabbing to our CFO (we work together) that she would totally be a surrogate for me if I wanted (the CFO was appropriately, hilariously stunned), so I don't really feel like I can trust her with the secret. Plus she treats everyone else's secrets like currency... I like to imagine my secrets are the exception but i know that isn't a logical belief.

I know she'll be hurt if I end up pregnant, especially because, due to the history, I'd probably tell her only after I told my direct team. She's super important to me and I'd LOVE an IRL confidant on the journey--daily symptom spotting, and especially in the event of a miscarriage. But I just don't know. Not telling her will damage our friendship, telling might hurt my career. Thoughts, friends? WWYD?
