What are some good love story movies that make you cry and are really sad?

I need to watch something really sad about love. I've tried bubble baths and ice cream. So now I think I'll try bubble bath, ice cream, and really sad love story moive all at the same time. I've already seen Love Story, A Walk to Remember, and The Notebook. If you've seen those movies there kind of my style. Please if you know any others like those movies please say so. Thanks.

Try P.S. I Love You and/or Deffinately MaybeI work at a movie rental store, those two are very popular and I have heard they are really sad.
