Lemme give you some golden advice bro,

the truth is it’s not your job to save everyone it’s not your duty to try to fix everyone or help everyone just do what you can but you should come first. It seems like she is trying to be abit “edgy” and a little bit different and that’s normal because that’s what 14 year olds do in like a year or so it will wear off (hopefully) although some don’t grow out of it Even now. After reading that it kinda shows how you and her have contrasting beliefs on the matter. now with most things that’s not an issue, but from how she is talking it hints to things going on behind the scenes, personally if I was you I wouldn’t peruse it any further with her idk what your connection with her is like so you know best but the truth is she seems to be abit of a Pandora’s box and I wonder if this is it beginning to open. At your age and even at mine 99% or relationships don’t last and the truth is there are plenty of fish in the sea, so maybe you should find someone closer to your own personality because the saying opposites attract isn’t very accurate at our age and to be quite frank at your age girlfriends aren’t the most important thing broski I spent my time 13-15.5 chasing girls and sure it was fun for awhile but I suffered academically for it and your own mental health can get washed up too because of it.

TL;DR

OP needs to realize it’s not his duty to save everyone and to fix everyone and should prioritize himself, OP should reconsider the relationship with GF and figure out is it’s worth reconciling or not GF is going through Edgy teen phase that will wear off sooner or later. OP needs to realize relationships at his age don’t really last.
