YouTube video?

I'm looking for a vid, probably from a movie, where a girl really likes this one guy, but then he breaks up with her cause' he likes another girl, but then wants the first girl back, but she doesn't want/love him anymore.
I know it may be a lot to look for, so anything close to this would be greatly appreciated.
Also, don't ask why I want this type of video. Suffice it to say I'm at the heartbreak hotel right now.
Also, there is not a particular video I'm looking for...
Thanks!!!!
