If I love you, Am I trapped forever?

In this book by M.E. Kerr the main character is named alan and he's seen as a popular kid in school. One day a new guy comes to school and everyone falls in love with him. Alan gets jealous of the new kid and a lot of times in the book the author tries to make Alan a character you wouldn't like but I couldn't help but see him as my favorite character. He had divorced parents and his father randomly tries to come back into his life, which isn't easy for a kid. Alan is a kid that has been through hard times so the way his character is, he is that way for a reason. Alan later finds himself crushing on the new guys mom which he hates himself for because he doesn't want anything to do with him. Deep down I think Alan hated the new kid because he was jealous of the perfect life he seemed to have. Overall I would recommend the book because it's interesting to see Alan's character change throughout the story.
