Also, meditate on love. Find someone you can really love for who they are, not how old they are or if they are terribly beautiful. When you do find someone to really love, find out if they really love you. If you love each other then get married. To be married is to be committed to loving each other for your whole lifetime no matter what happens. Love is a choice and a commitment. Marriage is the ground by which that love can grow and flourish.
Of course, God is the source of true love, so get connected with Him and He will guide your love and love through you. Love focuses on it's object and not on it's self. Love is the song that life is meant to sing. Hope you find it's song.
I know a unmarried couple who have been living together for 30+ years. True definition of soul mates. 3 children. When you hear the stories about a spouse dying and then the other spouse dies the next day due to grief, well this will be this couple.
Then you have 50% of marriages ending in divorce and probably another 25% of marriages that are unhappy but don't get divorced.
It's not as clear cut as you want to make it out to be.
