I think it would be harder if you told her how you feel.It's just like that with good friends.If it just happens, it happens.If you rush things everything will fall apart.Believe me, I've been there(and I still am )
maybe but then you'll never know?
i dont know what to suggest.
maybe you can subtly ask this girl if she has her eye on anyone at the moment. if she goes really giggly and wont give you an answer and asks you then she could well like you ?!
