Episode notes
Use The VAULT Method To Build A United Front
- Use the VAULT method to become a united, secure unit that sets boundaries and plans responses to in-law issues.
- Step two includes detailed questions couples should answer (values, roles, visit frequency, gifts, notice, who communicates).
Set Boundaries Only When All Three Conditions Exist
- Ensure three things before setting boundaries: willingness, importance, and ability.
- Without the partner's willingness, a clear sense of why it matters to them, and skills to set limits, boundaries will usually fail.
Meta-Communication Changes The Level Of Conflict
- Meta-communication means talking about how you communicate, not just the content of fights.
- Dalgleish shows examples: name defensiveness, take a beat, or state how shutting down makes the other feel alone.
