Everyone has their own "list" of traits they desire in a mate.
Once you find someone who fits the bill they are "the one".
In fact every new person we enter into a "serious relationship" with looks like “the one” until we realize they are not.
Truth be told there is no such thing as "the one"!
We live on a planet with more than 7 Billion people on it. Odds are there are far more than "one person" who has the qualities you desire. Hollywood and romance novels have romanticized the notion of "scarcity" and "obstacles" to make finding love a lucky fate.
The reality is most of us spend more time "excluding" than "including" when it comes to considering dating prospects.
If I say "the one" must be of my same race then depending on what that is I may have just eliminated 6 Billion people sight unseen!
If I say they must presently live in my country I may have eliminated 6.7 Billion, If I say they have to live in my same state or town that could narrow it down to a few thousand or few hundred people.
This is all BEFORE we get to things like height, weight, education, occupation, sense of humor, chemistry, hobbies and interests!
In addition to us believing they are “the one” it is necessary for them to believe we are “the one”.
Last but not least we say she/he must be liked by my family/friends and vice versa. It’s no wonder that by the time we get done EXCLUDING people there is ONLY one "right one" left!
No one is going to be able to read your mind, complete your sentences, or fill your days with sunshine for eternity. You determine how large your pool of potential mates is going to be by your method of including or excluding. Naturally the fewer options you have the more difficult it becomes to find a "suitable mate".
“Love isn’t finding a perfect person. It’s seeing an imperfect person perfectly.”
