I think this song is about a girl who is still in love with her ex that is dating someone else but they both still have feelings for her and she knows it.
"and i'm surprised we got this far
with that barricade but i want more
i would be a fool to let you let me quit"
The barricade being the new girlfriend and she knows he wants her to stop trying because it would be easier but she doesn't quit because they still love each other and she doesn't want to let that go
By the end, she's tired of waiting though and is thinking about moving on
