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.
