Jason Derulo - Whatcha Say Lyrics Meaning

I understood the song from the very beginning. Its about him cheating and then wanting the girl he cheated on back. And also that then girl he cheated on her with means nothing. In my opinion if I was the girl he wanted back (which ironicly I was a few weeks ago) I would\did not take him back. He made the choose all on his own and needsmto grow up and take responsibility for what he did. I wonder if Jason derulo actually cheated though. Overall I enjoy the song. It puts me in my feelings. ☺
