Start with their experience
If your adult child has pulled away, begin by trying to understand what the distance means to them. You do not have to agree with every detail to acknowledge that something has hurt or strained the relationship.
Take responsibility without demanding a result
A repair attempt should not be a bargain where your apology purchases immediate closeness. Name what you can own, ask what would help, and give them room to decide what kind of contact feels safe.
Rebuild through patterns
Adult-child repair often takes repeated evidence: respecting limits, not retaliating against distance, showing up reliably, and being willing to hear hard things without turning the conversation into defense.
