Like everyone else on here, I think this song is about a post-break up. But I think it's about the girl being the bigger of the two and he's promising to be an adult about all of this (I'll stand up as I shake your hand) and to get along with her but is probably being childish (this man is a fraud). At some point, he winds up asking to sleep at her place, on the floor, and then she kicks him out the next morning (the morning sun has come and gone). He finally realises his behavior is immature and promises to her, in his mind, that he'll correct all of his wrong-doings toward her and "someday, girl, we'll get along".
