In my opinion I think this book was left on a really bad cliff hanger, causing the four start rating.
I really enjoyed this book overall, it was entertaining, intriguing, a book you just couldn't put down. Natalie in my opinion made some really bad choices in friends, relationships, and decisions.
First, her best friend Phillips sister wasn't actually her best friend you could just tell. She was addicted to her phone most of the book, wouldn't try to fix her relationship with Natalie and then complain about it. She was annoying and changed herself for a guy (little tip of advice NEVER change yourself for a guy, If he really likes you he will like YOU not the person your trying to be.) She also never stood up for Natalie. But thats also just my opinion.
Second, Natalies relationships. Yes Phillip was a good person in my opinion, he stood by her side and believed her about not liking Owen, even when she said she did like him he still wanted to be with her. I admire that about Phillip, but there are also a lot of bad things about him as well. He was a hypocrite and made his rules only for Natalie, he would guilt trip Natalie, he thought popularity was everything, and I hate soccer (its not relevant but I just dont like it.) But in all honesty he never really saw Natalie as her true self. Natalie even said it her self, she said Phillip would think it was weird if he ever saw her doing her little quirks. Phillip isn't my favorite character but there are good things about him, but also some bad things too.
Third, HER DECISIONS! Oh my goodness, Natalie made the worst decisions in the world!!!! If she started falling in love with another guy she should have just broken up with Phillip instead of going out of her way to cheat on him. I know it wasn't like kissing cheating, but it was technically an emotional affair. I know throughout the book she would make a decision to love Phillip to only think about Phillip but how many times did she actually stay through with that plan?? Natalie in my opinion is the protagonist and the antagonist, yes she was fighting with some kind of mental disorder (my guess being OCD but dont self diagnose, she could have also had anxiety.) Natalie is a good character and she always strove to do the best for other people, she never wanted to hurt Phillips feelings but by keeping her emotional affair a secret made it worse. Phillip isn't the best person in the world but neither is Natalie, yes she's polite and always uses manners, but by keeping it a secret instead of breaking up with him and telling him the truth she made it worse by lying.
On to Owen. I dont really have anything bad about Owen but I also dont have anything positive about him... He was rude but not in a mean way, he lied but was open about his feelings, he was a reason Natalie broke up with Phillip but he also wasn't the reason. He wasn't my favorite character but he also wasn't my least favorite. He was nice when he needed to be and stayed away because Natalie asked him to. I respected him at the end of the book because he didn't jump into Natalies arms and start dating her after she came to him home. (kinda creepy though that Natalie did that.) I respected that he kept his boundaries with her and didn't give into her neediness of affection. But I also wish she and him got together because Owen would have helped with Natalies OCD things and would have been supportive the whole time. But I am glad that they didn't end up together.
This is all my opinion on the book, there were some parts I would have changed but over all it was a good book that I couldn't put down. You might be disappointed in the ending like I was but everyones different.
