It was a chapter ending (the dasha)
Relationships often end when a dasha period closes. When the planetary period that held the bond gives way to one that does not support it. This is why a relationship that felt right can still end: not because of a single mistake, but because the time that carried it ran out. Reading which period ended and which began reframes "what did I do wrong" into "the chapter closed."
Ketu, detachment, and sudden distance
When Ketu or a malefic affects the 7th house in either chart, it brings detachment. The sudden pulling away, the partner who emotionally checks out, the "they changed overnight" experience. This is the chart loosening a bond rather than a personal rejection. Naming it as detachment in the chart often releases the self-blame.
Why it hurt this much (Moon and 4th house)
The depth of the pain is read from your Moon and 4th house. Your emotional security and your inner home. A tender Moon or an afflicted 4th house feels loss more intensely and takes longer to settle. This is not weakness; it is your chart’s emotional wiring, and understanding it is the first step to healing rather than ruminating.
