Judging by the way you describe your dilemma, you want to help her and know that you shouldn't. That's also my answer. Just because you feel like you want to help her doesn't mean it's a good idea.It sounds as though she's using you, and you most certainly do not deserve that.
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.
