This may sound pathetic, but how could I prove to a girl that I love her without actually telling her "I love you" or things like that? I am a pretty shy guy and she tried more than once to make me be more sociable, but I just can't do it, I don't know why, I just can't communicate that much. So sometimes she gets a little pissed off because in spite of all her tryings, I still remain silent.
Could you give me an example of a situation that could prove her that I love her? I don't know ... a situation in which I would have to protect her or defend her. Help me.
And what should I do to become more communicative and what should I tell her to prove her indirectly (without telling it) that I love her?
I know for sure that I love her, because I can't stop thinking of her since the moment I first saw her. Even though sometimes she gets angry because I don't talk too much, she is a good person and more than once she helped me in various occasions.
