Iam female and it sounds to me like she loves u but is a nypho and does not want to hurt u by committing to u. She is young and will come around. Don't put your life on hold waiting, just keep in touch and it will happen when she is ready. It took me twelve yrs to marry the man I loved because we hooked up when i was 17. I didn't want to be another divorse statistic so we went through affairs and threesomes and experimented first after we made it through we realized we were meant to be together.
