Short answer:
Women stay with “shitty” men for many of the same reasons anyone remains in a bad relationship: emotional attachment, economic dependence, fear of loneliness or stigma, hope for change, low self‑esteem, learned patterns from family, social and cultural pressures, and practical constraints (children, housing, finances). Cognitive biases and signaling problems—overestimating positive moments, underestimating risks, or normalizing mistreatment—also play a role.
Key mechanisms (concise):
- Attachment and love: strong bonds and memory of good times make leaving painful. (Bowlby, 1969)
- Economic/dependent constraints: limited resources or childcare make exit costly. (Exit costs in rational choice models)
- Social norms and stigma: pressure to maintain relationships or avoid judgment. (Goffman; gender norms)
- Hope and intermittent reinforcement: unpredictable rewards (kindness amidst abuse) create powerful persistence. (Skinner; intermittent reinforcement)
- Low self‑esteem or internalized blame: believing one deserves the treatment or can’t do better.
- Fear for safety or escalation: leaving can be dangerous when abuse is present.
- Lack of alternatives and informational problems: not seeing viable partners or misreading signals.
Important caveat:
These factors are not specific to women alone—men also stay in bad relationships—but gendered power dynamics, economic inequality, custody expectations, and cultural norms make some pressures disproportionately affect women. For overview readings see: Bowlby’s attachment theory, Walker on battered‐woman syndrome (1979), and research on intimate partner violence and economic dependence (e.g., Kandiyoti on gender and bargaining; economic studies by Lundberg & Pollak).
