When someone is suffering from Betrayal Trauma, they are typically frightened, angry, confused, sometimes frozen in a state of shock wanting to just feel safe.
So safety and stabilization is the immediate mission with a betrayed partner.
Throughout the healing process the partner will constantly be pointed back to the issue of safety because that is the root to being able to trust again.
Regardless of how long she has been on her journey, she can have a plan, which will be formable as she moves through the recovery process, on day one.
This plan can benefit both the healing of the betrayed partner individually, and the healing of the relationship — if the betraying partner is willing to join in.
