d0ug,
Take this as a valuable lesson.
If any of your older relatives tells you that you are too young to
be in a relationship, this is the reason why.
The good news is you are a sincere guy, and that attribute should
put you in good stead with future BGR.
Don't pester her anymore. We have to learn to accept defeat
graciously, in order to taste success next time..
Study hard, and continue to be a good person!
