I have no idea! I had always wondered that myself because that seems weird to me too that someone would think that and I defietly don’t think it’s true because when she performed it live back in 2007 (and I’ve seen 10+ videos of her performing it live so she probably said this several times) she would introduce it as being about when you’ve got a boyfriend who’s got an ex-girlfriend who doesn’t know she’s an ex-girlfriend. I’ve never heard her mention Austin which she probably would if it were about him and I think it’d be weird anyway if it were about him because she put it in her point of view as if she were his new girlfriend. So my guess would be that it’s either about Drew or Sam depending on if it was written in 2005 or 2006 which I can’t quite tell because the picture I have of the demo CD it’s on is so low quality that I actually can’t tell. haha I think it says 2005 which would mean Drew but since it didn’t make the first album she didn’t start performing it until 2007 because she was thinking of putting it on Fearless. Forever and always didn’t replace it though because she said she just added it to the end. Which makes me think she did that with White horse too and was originally planning on putting 11 songs on there just like she did with her first album. I don’t know for sure but that just kind of makes sense because then on Speak now she would’ve put 13 songs on there but then she wrote Never grow up and added that on. Not sure about Red but I imagine she’ll never have an album from now on with more than 16 songs on it so from now on there’ll probably only be 16 or less because 16 is already a lot. 1989 only has 13 songs by the way, that was confirmed by Target along with the co-writers of each song. She only wrote one by herself (number 11) and the Dianne Warren co-write didn’t make it on there. :/ Not even on the deluxe version which has 3 bonus songs and 3 voice memos (I’m so excited for those!) but she did write 3 to songs with Ryan Tedder to make up for it. Oh, and I’m going to add 1989/live stream facts soon (and I can confirm them because I was there! She touched my hair!), I just haven’t yet because I’ve had limited internet access for the last few days.
