Questioning

Here are a few questions that I have always had.. What is the difference between like and love? Like is such a puny thing when compared to love... and yet, you making this huge jump between like and love. And if it is more then liking and less than love, what do you call it? I always call it falling. You know there is going to be one thing that is going to push you over the edge and into the abyss known as love. And then, what is the difference between love and in love? It is a huge difference. But linguistically its such a small difference. It is just one word. One tiny, two lettered word. But mathmatecally it is a huge jump. You'd do anything for someone that you are truly in love with. And how do you know if someone is the one? What is "the one"? If you don't know what the one is, how do you know if you have found him?
