Is NOBODY wrong in the post ? POST : I’m on mobile, sorry for the shitty formatting.

So my girlfriend and I have been dating for 6 months and everyday  was fantastic with her until the luster wore off.  Around 4 months into the relationship I noticed how negative she was.  Every time I’d call her after school she’d always be on about something else. Whether it be her parents, friends, food, etc. it was tiring encouraging her 24/7 and at one point I’ve had enough. I broke it off I just couldn’t take it anymore. Am I the asshole?
