Songs that remind you of past relationships

[Toki]

I always found listening to positive music (I got into slipknot after my last relationship) but I digress, there's usually one song that reminds you, or basically sums up why the relationship failed. I happened upon the song 'Snuff' awhile ago, and thought that it pretty much covered how I felt about the whole thing. So what song reminds you of your now (perhaps recently) dead relationship?

Taylor Swift's Breathe...just about sums about the truth about relationships and breakups...people change...life changes...even if we don't want it to...sh*t happens and we just have to move on...
