"After 5–7 days of unusually high investment — she texts first, suggests plans, is warm and present — she goes cold with no explanation."

What she's actually testing

Whether you built structural dependence on the high-investment period. This is the short game in action: the sprinter gives everything at once to create emotional dependency, then pulls back to see if you chase. The chase confirms you were calibrated to the high-investment baseline — which means she has leverage.

Why it works on most men

Seven days of warmth is enough for most men to reset their baseline expectations. When the warmth disappears, the gap feels like loss — even though nothing real changed, because the warmth itself was a test. The man who adjusts his behavior after the flip confirms that the warmth worked as leverage.

The response framework

The obvious: don't react to the flip. Maintain the same frequency you would have held before the warm week. The disruptive: read what actually happened. The week of warmth wasn't a gift — it was a test. The coldness isn't withdrawal — it's the data collection phase. The man who played the long game doesn't change his behavior in either direction: not more investment during the warm week, not more effort during the cold one. He has a consistent baseline. She's trying to find it. When she does — when she realizes your behavior doesn't move based on her investment level — the game changes.
