/cgl/ - Cosplay & EGL

I have a friend I cosplay with. I support her in every decision she makes, promote her, and do everything for her to get noticed because she has confidence and trust issues. I just want to make her happy with herself once again. Yet she doesn't help me back, talks behind my back, and she is now, how she says, "more popular now" and wants to hang out with other people.

I don't know what to do /cgl/. I've tried talking to her about it, but she ends up making herself look like the victim and makes it sound like I use her instead especially since, according to her, she is "more popular" now. I'm stuck because I don't want our friendship to end sour but at the same time I want to tell her how I have been feeling about this whole situation without her getting mad
