What statistics support Flora Dunn's claims about settling in relationships?

Flora Dunn’s content highlights patterns that are well supported by relationship research, even if she does not quote specific studies in every video.

Broadly, research shows:

1. People who feel they “settled” report lower relationship satisfaction and higher odds of breakup over time.
2. Feeling you had poor options when you chose your partner is linked to more regret and resentment later.
3. Regret about partner choice predicts lower overall life satisfaction, not just relationship unhappiness.

Would you like references to general studies on regret and relationship satisfaction, or stats you can directly quote in a discussion or project?
