Dear Diana,
I have been with this girl for over three years now. Things are going fine, except the fact that her sister influences her a lot. She is older to my girlfriend and ever since their mother passed away when they were young, her elder sister has been a mother figure to her. I detest her sister as she keeps telling her stuff about me. According to my girlfriend, she is cautioning her, but I feel this is interference. Last week, she told her that she had seen me with a girl on the seafront. This was wrong information as I was out with some relatives who had come down from Ranchi and were keen to visit the beach. Whatever her sister tells her, she blindly believes. How do I tell her not to believe every word she tells her? My girlfriend is 24, but can't think for herself.
