From my experience, communication is probably the most important factor within a relationship. The fact that your girlfriend lies at all is a huge issue and needs to stop. How can you trust her on bigger issues that may come to the forefront in the future, and possibly with children involved, should she continue to lie?
Your girlfriend may have issues that contribute to her inability to tell the truth from her family history, etc. If you care enough, you can help her delve into this with professional help, however, you need to sit down with her and let her know that this cannot continue. A good base to any relationship involves open, honest communication.
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.
