Who sang that song about finding his girlfriend cheating on him in his bed or bedroom?

It came out about 6 years ago I think and it was like an alternative rock song. I don’t know the name of the group or even the song, and I cant even really remember any of the lyrics. I now the song was about him catching his girlfriend with another guy in his bed or his bedroom or something like that. He was maybe going to get revenge or something. I remember a lot of anger behind the song. I wish I had more info but I don’t, hopefully someone will know this song.
