Your Soul mate will be somebody who marks a before and after in your life. It is not the human being everyone has idealized, but an ordinary person, who manages to revolutionize your world in a second.
I do this all the time. With my husband, our children, a close relative, a friend. Sometimes I just randomly get an incredible overwhelming feeling and am reminded of his much I love them and how blessed I am to have them in my life!
Throughout life you will meet one person who is unlike any other. You could talk to this person for hours and never get bored, you could tell them things and they won't judge you. This person is a soul mate, your best friend. Don't ever let them go.
