Me and my girlfriend, both 13, have a hard time keeping touch. Her parents don't know anything, because she doesn't want that famous "talk". She acts sort of indifferent around me and likes to laugh at my lame jokes. Is that a sign of nervousness? We both love each other very much, but we never hugged. We're always surrounded by other students and I don't have the guts to ask her for a hug. What do I do? I don't want to stay like this!
