I guess it means that if two people really love each other, they'll find a way to be together or make it work.
It means that if people have false hopes, it keeps them alive a little longer. So that's what they say to themselves. Love never found a way in my family. It's just a bummer. I want to fix it, but I don't think I can or will.
Same thing as saying nature finds a way except you put a human personality and it becomes love and so does things in physics frankly so... :-)
