The meaning of the numbers comes from numerological tradition; it isn't a measure of your personality. A full portrait needs your first and middle names, your last name at birth, and your date of birth. How we calculate
Your name and theirs
The number of each name, and the number of the bond, which comes from adding them together. A symbolic game: what your two names say together, to be read as a metaphor, not as a verdict on your relationship.
