It's not wrong... I would use the word brave. Can be a bit of a Russian roulette when being totally honest with another... even one who we consider close.
My best friend of almost 30 years knows nothing about my mh issues. From observation and experience of his attitude and general outlook, he would neither understand nor want to know and it would create tension and perhaps even severance of our friendship.
I don't think bad of him for this... I just know the limitations of that relationship. People have different strengths and 'loyalty' is not a black and white scenario.
Would he trust to have me at his back in a tricky situation? Yes he would, as would I. We have a silent understanding that some topics and situations are just a no go... that's life and that's people
Don't let it get you down too much Fuzzy, you'll probably be surprised by those you didn't expect to support you... support you, more so than those that might let you down
