So, another thread made me think about this line, and figured I'd start a new thread instead of derail.
So... do you agree with the statement, "I don't keep anything from my partner, no matter what?" Do you think it's good to tell your partner absolutely everything, or do you think that telling him (or her) absolutely everything you find out about other people (particularly when they've said it to you expecting you to keep it to yourself) is quite wrong?
I mostly tell DP everything... but if, say, a friend confided in me that she was a victim of sexual assault, I wouldn't be running off to DP to tell him that. I figure that's such a deeply personal thing, and it would have taken her a fair bit to share that with me... who the hell am I to decide that my partner deserves to know that bit of info about her?
Or even to a lesser degree - your kids confide in you, and ask you not to tell the other parent. In some situations, it makes sense that you'd tell the other parent... but sometimes... well, I am still annoyed that my mother told my father that I had my period. I was 11 and had already had my boobs and pubic hair since 8. It was just another thing I was annoyed about happening prematurely.
Fair enough if she told and he kept his trap shut and I never knew he knew... but instead, he waltzed in to the loungeroom a few minutes after I had told her and said, "So... I hear you're a woman now. Make sure you take care of that properly."
I could have died, and from that moment, I knew I could never trust my mother so stopped confiding in her. It's such an innocent thing, but it meant a lot to me at the time, and her blowing my trust could have been horrible had something serious wrong happened to me in the years to come where I would have needed to tell her.
So, I guess, I basically tell DP most things... but if it's very personal, or I know that this person is seriously trusting me, I don't tell him. He doesn't even know about DD's "boyfriend," (she's 7... and from what I can gather, he doesn't even know he's her boyfriend... lol. But still, she's trusting me with this secret and asked me specifically not to tell DP... so I haven't... just because I realise doing so, and him letting slip, might mean she realises she cannot trust me in future and I'll miss out on being there for her when she actually needs me).
