but it has nothing to do with trust. You can trust someone to keep a secret, but not to be disappointed. an earlier post argued against assuming someone's feelings - in that case you can't be confident what the result of communicating your feeling are, unless you are confident b/c you don't care.
It’s all about trust. You can’t develop an intimate relationship with someone who hides their feelings. Being fake in a misguided attempt to avoid disappointing people is deeply unkind (and probably exhausting).
