Girls, please help me...?

There's this girl i met and we went for a trip. She is always staring at me. When i look at her, she only smiled... I tot that's eerie. And then, at one of the activities (water sports), she kept holding on to me. Like.. she scared of the waves pushing her away. So she tried to hold on to me. Then at the boat, she requested to sit with me. Is this very weird?
