“My adult son has cut off contact with me”

What could be going on

Emotional cutoff: Fits if distance is how unresolved hurt is being managed; check whether talk had become impossible.

Boundaries: Could be a protective limit; check whether earlier, smaller requests from them were heard.

Rupture and repair: Check what ruptures went unrepaired; acknowledgement often matters more than explanation.

Separation-individuation (Mahler): Could be a late push to become separate, especially if closeness felt controlling to them.

Grief (complicated, disenfranchised, anticipatory): Your own loss is real and may be disenfranchised; check whether you have support for it.
