What's a good song about overprotectiveness?

I have to do a project for the book Of Mice and Men where we need to find a song that relates to each character. I need to find a song about a character in the book named Curley who's protective over his wife and doesn't want her around other men or leave to go anywhere and when she died, he goes and tries to kill the guy who killed her. So, I thought that I should find a song about being overprotective or for protecting someone like that grenade song (i forgot what it was called) by Bruno Mars, but my friend already took that song. I just need this one song and then I'm going to be finished with the project.
