What is difference between "LOVE and LIKENESS"?

Actually, few days before, a girl came in my home, and we just start talking each other and after two day we went for dinner because our family want to see us togather but i only want to love marriage not arrange marriage, and after that night, i told her that i love you and she just said that she didn't think like that. After a mouth i felt that she is my love. But she was so beautifl too. And now i am confused that she is my love or i just only like her, just anybody, can help me please?
