"I think it's impossible to hide how obvious it is. The day that our single hit the airwaves, my ex-boyfriend said he was going into rehab and canceled their tour. I haven't ever said right out who it was about, but it's about the big relationship I was in, and the whole breakup, which was really long. The breaking up and the hard stuff in our relationship happened sort of after I was out of the spotlight for a while and writing. It wasn't in any way public. I was trying to be kind of discreet about it, and then he totally came out and said he was going to rehab. It was shocking to me. It kind of made for a more interesting story."
