Well you're in between a rock and a hard place mate. If you really love her tell her straight up. What's probably happened is that what happens to all long distance relationships in the end run, you've grown apart.
Perhaps you havnt but she has. Maybe at home she already had her eyes on a guy? It depends on her answer you need to have a realistic conversation with her.
Over the phone or something where she cant answer in one sentences. You need to tell her how you feel and ask her about her emotions. If she says she doesn't know or she does love you but she can't for some reason maybe you should visit her.
Perhaps she's in the same position as you? The only way in finding out is communicating. Good Luck, I wish you well!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
