Understanding the Multidimensional Parter Trauma Model: A Roadmap for Healing after Betrayal

If you’ve ever wondered, “Why am I reacting like this?” after discovering betrayal, this episode is for you.In today’s conversation on Confident Again, Jane walks you through the Multidimensional Partner Trauma Model (MPTM) — a research-informed framework developed by APSATS (the Association of Partners of Sex Addicts Trauma Specialists). This model was created specifically for partners experiencing the trauma of intimate betrayal.For too long, betrayed partners were labelled “codependent,” “too sensitive,” or “overreacting.” The MPTM shifts that narrative. It recognises that the anxiety, hypervigilance, rage, numbness, and confusion you may be experiencing are normal trauma responses to an unsafe reality — not character flaws.At its heart, the MPTM is built on one powerful truth:Safety is the treatment.What You’ll Learn in This EpisodeJane unpacks the three core phases of the MPTM and helps you identify where you might be in your own journey:Phase 1: Safety & Stabilisation When discovery hits like an earthquake, the priority is re-establishing safety — physically, emotionally, and relationally. This may include boundaries, support systems, trauma-informed therapy, and, for couples pursuing recovery, structured therapeutic disclosure.Phase 2: Remembrance & Mourning Once some stability is restored, space opens for grief. This is where meaning-making begins — processing anger, sadness, shattered assumptions, and the loss of the relationship you thought you had. It’s also a time to notice what hasn’t been taken from you: your resilience, your strength, your core self.Phase 3: Reconnection Here, healing deepens. Identity is reclaimed. Beliefs are reframed. Couples (if staying together) begin weaving a new relational story grounded in truth and accountability. This is where post-traumatic growth begins to gain momentum.Importantly, these phases aren’t linear. You may move back and forth between them. That doesn’t mean you’re failing — it means you’re healing.Jane also shares three simple ways to align your healing with the MPTM framework:Notice your body’s cues and respond with safety.Replace self-blame with trauma-informed language (“This is trauma speaking.”).Seek support from professionals trained in betrayal trauma.Healing from betrayal takes time — often years, not months — but each step toward regulation and self-compassion matters.Ready for Practical Support?I've created a gift for those nights when sleep won't come.
