It seems to me that it is a story of a failing relationship, but the last verse is the aftermath of ending something that you think makes you miserable. Boy starts to resent girl (for having him "up against the wall"), and the feeling becomes mutual. The two hate each other and by the end of it he misses her and thinks "It’s almost that I wish you had me up against the wall".
Almost like saying that he'd take the worst just to have her again.
