New Moon?

I saw the first twilight and was more than impressed with the movie all except one part. The next movie in the series is new moon, which is a great movie except for a one a problem found in the first one. They both end in a doubt way that makes you really pissed off about the movie. In the first one you end with Bella and Edward dancing and Victoria the vampire running away. In New moon the end consists of Edward asking Bella to marry him and her not giving and answer. My question is what the heck is wrong with these movies and messed up ending.
