That's understandable Jarylee, I work very much the same. Internal stress for me is horrible, I have physical effects from stress and I very much need to talk to release some of it. A very, very private friend of mine has just been given a matter of months to live and heck yes I went home and cried and told DP.
For things that won't cause me any stress/worry - like a friend's hemmorhoids - well I don't see why DP needs to know "everything" iykwim. I'd consider that breaking a friend's trust. And I'm sure he'd actually appreciate not knowing some things really... like that.
