Case. One partner lost their job; money anxiety and a hit to self-worth spill into fights.
Model. An external incident (lost income) plus an internal one (self-worth) add up to double load. Blame here is a second failure on top of the first.
What helped. A team against the situation: support instead of reproach, a shared plan, separating anxiety from attitude to the partner.
Lesson. In an income crisis the partner is needed as an ally, not a critic.
