I'm trying to find this movie, its about a guy that is going to his wedding but he mets this girl and he ends up liking her, there is this scene in a hotel room that they shared, at the end of the movie he was going to tell his fiancé that he wants to brake it off but when he sees her, he deicieds that she is all he ever wanted. The other girl was waiting on a bench for him but knew he wasn't going to come back, so when he came out to tell he he was staying with his wife, she was already gone.

Could be "Forces of Nature", Sandra Bullock.
