Which Lover Is The Right Lover?
Numerology may be most helpful to you in this matter. Typically, life-long soulmates have aligned life paths. 1 and 7 are aligned. 2,4, and 8 are aligned. 3,6, and 9 are aligned. If 5s are meant for lifelong partnership which is rarely they case, they do best with 7 or 1 or each other.
From Illes, Judika. Encyclopedia of 5,000 Spells (Witchcraft & Spells) (p. 119). HarperCollins:
Should you be lucky enough to have a choice of wonderful lovers, this spell helps you choose wisely between them. One red apple is required to represent each potential love. Carve a person’s name into each apple using a rose thorn. Place the apples in a dark secret place where no one else will disturb them. They must not touch each other.
Check the apples daily: the apple that resists rotting, that stays freshest longest is your true lover. Once the decomposition process starts you may wish to maintain a more frequent eye, to prevent confusion and mistakes.
