Practices that may help

  1. The Investment Model of Commitment: Why People Stay (and Why They Leave)
    Caryl Rusbult’s Investment Model proposes that commitment is driven by three factors: satisfaction (how good the relationship feels), quality of alternatives (how appealing life outside the relationship seems), and investment size (what you’ve put into it that would be lost on leaving). All three are modifiable — and understanding which is weakest gives a precise target for strengthening commitment. The model has extensive empirical support across diverse relationship types and cultures.
  2. Making your investments visible to both partners
    Name and acknowledge the shared investments in the relationship — children, history, shared projects — to both parties.
