I could not support the relationship in this book at all. They have a cute moment when they first meet, but everything after is terrible communication, misinterpreting things, jealousy and overreaction. And the friendships in this book aren't much better.
There's also some gross body image stuff in here. The main character is constantly insecure about her looks because she's not hot/model like beautiful. And people keep reassuring her that it's okay. Not because there are things more important and those are horrible standards to be held to, but because she's a different sort of beautiful, the sort that lasts, while the other will fade and be worthless.
There's some good getting into the mindset of the way awkward teenagers think and their insecurities, but the entire book was focused on the progression of a relationship I did not find healthy at all.
