What are some alternative/modern sad love songs?

I feel like listening to some new songs and I want them to be sad love songs. My favourite bands/singers are Lovedrug, The Red Hot Chili Peppers, Fireflight, Paramore, Switchfoot, Taylor Swift, Jason Mraz, Copeland, Coldplay, Owl City, Anberlin, Metric, Yellowcard, Rise Against, Krystal Meyers, Relient K, & Regina Spektor.
