Couples can vary widely in terms of:

  • Gender composition (same-sex, opposite-sex, non-binary, etc.)
  • Relationship structure (monogamous, polyamorous, open, etc.)
  • Legal status (married, domestic partnership, cohabiting, etc.)
  • Age differences
  • Cultural and ethnic backgrounds
  • Religious beliefs
  • Presence or absence of children
  • Living arrangements
  • Communication styles
  • Shared interests and values

This diversity reflects the many ways people form intimate partnerships and define their relationships. Each couple is unique in how they navigate their connection.
