Is AUTHOR wrong in the post ? POST : i'll keep it short and sweet

i'm a guy and i have been in a relationship with this girl for 1,5 years now and she's great and i love her. But recently we got in an argument about the way i dress. She says that the way i dress is hideous and way too emo but i don't really think so. She says my favorite outfit is the worst; it's black jeans, a pink sus boy x lil peep shirt and a black jacket. she also told me she despises my black and pink socks which i love. she told me that if i would'nt dress more like an adult that she was gonna break up with me. Btw i am 19 and she is 18.
