Is there anything you wouldn’t tell your best friend?
If I had a significant other, I wouldn’t tell my best friend things that were going on between him and me. I believe that those things should be kept private and getting a third party involved just complicates things and is not good. A therapist is a different matter but a best friend: no.
I also wouldn’t tell a best friend some of my deepest and darkest secrets, and I do have some that only my therapist has heard and no one else on earth as heard. There are some things that are just too personal and private to share even with your best friend. It would serve no purpose. She would not be abe to help me with them and who knows where my secrets would end up?
There are just some things that shouldn’t be shared. I’ve learned this the hard way.
