Hello Ipodlover77 & welcome
I am sorry to hear you feeling so down.
Young love can be wonderful, but also painful.
Just putting your feelings on here should help you a little bit.
She may have done this because she was missing you.
She may not know exactly what she wants.
Both of you could change a lot in the next few years.
How old are you both?
Probably the best thing to do is wait until you can actually sit down together and talk ~ and see how things feel then. I know that it is hard, but young love sometimes can last a lifetime and sometimes it's just brief and sweet. Who knows what category this falls into, but it would be worth having a serious talk with her about everything.
Good luck
