Relationship advice please?

Hey I have been in this exact situation before. I am a senior girl, and when I was a sopre, I was dating an older boy. I was not allowed to ride in cars with boys until I turned sixteen and my boyfriend could drive; so I could almost never go anywhere with him and our friends because they would all ride in a car together. My parents were very protective and hers seem like that as well. She is most likely still her daddy's little girl and she will have to earn her way to her freedom. Some more freedom will come with age, but some freedom can be earned by your girlfriend sitting down and having a heart-to-heart talk with her mom and especially her dad. She needs to let her parents know that she will make responsible decisions and she trusts you and likes you a lot. I did this with my parents and they slowly began to make changes with my hanging out with boys. Over time, parents become more lenient and they soon forget about the old regulations and such. Now, two years later, I am allowed to hang out alone with my boyfriend at his house or mine! It's changed a lot since I was 16 and I feel your pain. Good luck! :)
