Why can't i stop thinking about The Maze Runner Trilogy?

I've just recently finished reading the first two books in The Maze Runner Trilogy (The third one hasn't come out yet) and i find myself CONSTANTLY thinking about it. Especially the second book. In pretty much ALL of my free time i keep thinking about 2 of the main characters (Tom and Teresa) and how the should get back together and thinking about what they could have been. What's weird is I've NEVER EVER felt this way about other books and I've read TONS of books before and this is the first time something like this has happened. i think i'm becoming obsessed. I find myself dreaming about it, thinking about it first thing when i wake up in the morning and also the last thing before i go to bed!!! I even find myself daydreaming about this whole situation of Tom and Teresa during school and i'm just wondering if there is something wrong with me?? (This is also weird because i'm almost 17 and a guy, and i'm not even one of those creepy loner dudes either sooo if someone can help it would be GREATLY appreciated.) Thanks :)
