thomas, it sounds like your high school girl didn't have very much to say when you told her all this?? Did she just listen and keep quiet?
Sounds to me like she doesn't feel the same way...
Just be glad that you got a chance to say it all...it's obviously been on your chest for a long time, but it doesn't seem like much is going to come of it.
Maybe email her and tell her that you're glad you told her everything, but you're happy to be friends and you're not expecting anything from her.
And then get on with your life with your current g/f
