That's a shame. I think sometimes people who have a lot of money become defensive. They think that people only want to be friends with them because they have money. That everyone's trying to get something out of them. They don't know who they can trust, they always have their backs up. It will be hard to prove your loyalty to her. You said you were friends with her for a long time, that should be proof enough. Were you friends with her before she had money? I know you said that this post is not about money, but I believe that money is the reason she is like this.
