What does research say about Sternberg love in long-term marriages?

Long-term couples typically shift from romantic love to companionate love. High commitment and intimacy sustain marriages across decades. Passion naturally declines but can be maintained through effort, novelty, and ongoing attraction work.

What's the most stable love type for marriage?

Companionate love (intimacy + commitment) is the most stable and common in long-term marriages. Consummate love (all three high) is ideal but requires ongoing maintenance. Both outperform empty love, which is vulnerable to dissolution.

Do couples who maintain high passion have better marriages?

Not necessarily. While some couples maintain passion, research suggests that intimacy and commitment are stronger predictors of satisfaction and stability. Couples at peace with passion decline while maintaining intimacy report high satisfaction.

What destroys long-term marriages according to this research?

Loss of intimacy (emotional distance, lack of communication), broken commitment (infidelity, emotional affairs), and unresolved conflict are primary drivers. External stressors exacerbate these issues if the foundation is already weak.
