Situation 01 · The one who rereads the messages
She texted him in the evening, he replied curtly: "ok." From that minute she can't focus on anything: she rereads "ok" again and again, parses why it's so dry, whether he took offense, whether she ruined it that morning. By night she has a full breakup scenario in her head, though exactly nothing has happened.
✗ The wrong way out
Write again: "you're not mad? everything's really okay?" — and wait for reassurance. It'll soothe for five minutes, then anxiety latches onto exactly how he reassured, and the lap starts over. A begged-for "it's okay" treats the symptom and feeds the loop.
✓ The right way out
Name it anxiety, not analysis, and bear "I don't know": I won't figure out from two letters what's inside him, and that's fine. Don't fill the silence with the worst; put the phone down, let the evening pass. A calm reply — if one's needed — write in the morning, from clarity, not from the peak.
