about love but not love

When first time I looked at him . There were something made me feel that I've known him since ago . I have a feeling when he'll come near me . When I looked at him, my heart sound like a clock. I never felt it before . Before I met him, I just thought that love was just love, there was not a feeling beside love. I often think love can make someone's life broken. Because A half of my friend felt broken heart when they ended their relationship. But it's not a problem when I looked at you . There are a strange in his eyes. There are a expectation in his face. nd there are a future in his heart. But I afraid to love him . Because he is the first for me . I never felt in love seriously like I fall in love with him. But I still not steady that whether I love him or not. So what should I do ???
