I have to agree with DarkMeLegendary. Some of us coming into Adulthood just want to be free to make our own decisions, and make our mistakes without feeling like we are letting everyone down.. being a disappointment, especially to our Parents. I ran off to Atlanta GA when I was 21 because I felt like my Family "and some friends' had me under a microscope, watching my every move, always with their 2 cents,.. so to speak, and I just wanted to be free to venture out and explore, not bother or hurt anybody!
It actually helped me a lot to be on my own for awhile, to realize who I am as an individual, away from all the people who thought they knew what was best for me. Some of us just need more space to grow than others. What ever you do, don't worry, just Pray that you've taught her well, and that she will be safe.
