Is the movie twilight the same as the book?

There are many such as the cooking scene in the movie where the Cullens (apart from Edward) are cooking for Bella. This part is not in the book. Also, where the bad Vampires (James, Laurent and Victoria) are "Feeding", (In the boathouse and factory). Those two parts in the movie are not in the book. Also, near the end of the movie, where she has to get away from Alice and Jasper, the part in the movie is slightly different.

in the book they often tell I love you to each other while in the movie I never heard if they told each other I love you.
