You can give any interpretation to Ashlee Simpson songs, she and her team writes them so u can relate.
This song is about someone who's done by now, after all the things they went through. He was careless about the relationship and more into the fun, she was more into the relationship - that's why she sings "you're still dancing on the floor" "you're running wild without me, Can't you see, I'm not enough-" - so she is not what he really needs and it's not her fault.
