No, no, no. This is song is about how, girls always think things through, and over analyze everything, and guys, on the other hand, just don't care. They all have their insecurities and problems, he was so scared of getting close to her, and giving her everything, that he practically shut her out, he built up a wall, and now he's got find a way around it, cause he screwed up by not giving her everything, so she's saying, you gve up before we even started, she had so much faith in him, that he comuld suck it up and actually try to work things out in the relationship byut instead he sucked, and just gave up on a good thing. Cause guys, just don't care, and when they do, they scare themselves off by bulding up a wall with their girlfriends, and they can't find a way to get out of the hole they dug themselves, so they just give up a good thing.
I know, amazing. (:
