She doesn't sound like a good person at all. You should stop pursuing a friendship. She already admitted she is jealous, you are a threat to her.
Maybe she feels she needs to compete with you so she ignores you. She says mean things about you and does things that show her dislike of you. She is the problem, not you.
Just be nice to her as you are to any stangers but stop trying to be her friend.
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.
