I Recommend : The Last Kiss

It's a great movie, not that starring by the lovely and amazing Rachel Bilson, but besides the fact that the screen-play, the decoration, the music and the fashion are the best, but the movie is very good that you can learn much stuff out of it, it tells how much confusion and burden can/will you take from a relationship, where your fears and desires might lead to ways that you WILL regret them later, where the place of forgiveness means that you will take the rest of your life repenting what you did and try hard to let the other partner let it go and get over it, music selected is the best, the movie ends with an amazing 3 minutes length of Coldplay's "Warning Sign" and Impogen Heap's "Hide And Seek".
