Don't need to hit...talk to her try to spend more time with her. Move to
get her away from the people who influence her. Everyone wants to be
good it's there suroundings that change who they are. There is something
in her mind that does not let her open up to you. Take your time and
learn why this is. I know she loves you and you love her. Never yell at
her either, this just closes the door to the problem. Take her out just
you and her, little by little she will open up. My number one thing I
would do is change of enviroment. Hope the best for you and her...Mike
