Union lines — those horizontal creases on the edge of the palm below the little finger — have been read as marriage markers for centuries. A line that ends in a fork (a Y-shape or a split) has traditionally been interpreted as separation or divorce.
Some readers distinguish between a small fork (disagreements but staying together) and a wide fork (a clear parting). Others see the direction of the fork as meaningful: a fork pointing toward the heart line suggests emotional reasons for parting; a fork pointing toward the fingers suggests practical or external reasons.
Modern, more cautious readers note that a fork can simply indicate a relationship that changes form — marriage to co-parenting, romance to deep friendship, or a shift in priorities. Not every fork is a funeral.
