Case. One spouse keeps a close tie with an ex-partner; the other feels threatened.
Model. An open port to an external system that once had high access. Even without ill intent, it’s a risk and a source of anxiety.
What helped. Transparency and an agreement on boundaries comfortable for both; the priority is the current couple’s safety.
Lesson. “We’re just friends” doesn’t cancel the partner’s right to peace of mind.
