Why Does Someone Go Silent Instead of Telling You What Is Wrong?
Silence is a message with no fingerprints on it, which is the entire reason people reach for it. The quiet happens because of: 1) plausible deniability, since nothing was said, so nothing can ever be quoted back at them 2) negative reinforcement, because going quiet has reliably made you come and find them, and that worked every time 3) conflict avoidance, since saying the actual thing risks a conversation they do not know how to win. You can answer a sentence. You cannot answer a vacuum, and that is the design.

How it actually plays out
Say you are here when they want to talk, then genuinely stop guessing.
