How can you compete with a husbands mistress she's 20 years younger than you?

Competing with a husband's mistress can be emotionally challenging, but it's essential to focus on self-worth and personal growth. Instead of comparing yourself to her, invest in your own interests, health, and relationships. Open communication with your husband about your feelings and needs is crucial; consider seeking professional support, such as counseling, to navigate this complex situation. Ultimately, prioritize your happiness and well-being, regardless of external comparisons.
