With over 7 Billion people on the planet I suspect each of us has many soulmates! However I do not believe there is a (sole-mate) or only "one" person who "gets you", connects with you, shares your same desires in life.
The concept of "the one" is based upon our natural tendency to (exclude) rather than (include) when it comes to finding love.
For example if a person states "the one" has to be a member of their own race that automatically eliminates (Billions of people) right there! If you went on to say he/she must have the same religious belief that will cut down your options by several billions more.
We narrow things further by stating "the one" must reside in our own country, state or town. All of this is before we get to height, weight, age, occupation, education, hobbies/interest, and goals....etc Last but not least our family and friends MUST also like him/her and vice versa!
It’s no wonder that by the time we get done EXCLUDING people there is ONLY one "right one" left! I believe once we decide what’s "really important" with regard to traits in a person we are likely to find "the one" sooner rather than later.
Each of us is looking for specific traits in another person. In addition to us believing they are “the one” (it is also necessary for them to believe we are “the one”.) Having mutual feelings is the challenge. Chemistry is also a requirement.
Lets assume you are looking for someone who has the following traits.
Attractive, Positive, Affectionate, Considerate, Loving, Healthy, Romantic, Passionate, Great Sense of Humor, Intelligent, enjoys traveling to exotic destinations, Honest, Trustworthy, Loyal, Dependable, Financially secure/responsible…etc
(Surly out of 7 Billion people there must be more than “one” person who fits this profile!)
