@NotTelling Saying nothing is
not a solution to the question of "
How can I let Bobby know that he's been cheated on while minimizing the fallout for myself from Sarah". I do accept and even advocate "non-verbal communication" as a form of interpersonal, but for it to be an answer to a communication question the silence would have to "send a message". This answer advocates
inaction, and ignores both the question and the conscience of the person asking it. The problem outlined in the question remains, hence it is
not a solution of any kind. —
