Songs that say "it's over" but not in a hateful way?

….but not pop stuff.

My ex just sent me this and I don’t want to write the longest email ever explaining him that I can’t go back, but it’s not that I don’t love him. I love him as a friend, or a brother with huge problems. I’ve told him that yes we can be friends, but not now. He keeps calling every fucking day. Three or four times. I answer once a week or so. It’s sad, really. It was a very good relationship at first, then things got awful and then colder than the ice age.

So.. I want to answer with a song that says it’s over, I won’t change my mind but no I don’t hate you. Or something.

Oh hell, now he’s texting me
