Well the first verse tells like how a guy broke up wif his gurl cuz he didn't want his friends to really know but when he did break up with her he realized he really loved her.
In verse 2 its tellin how hes rethinkin if he did love her or not but he can't tell. So hes tryin to tell himself hes not a bad guy for doin what he did.
In verse three it shows how hes really confused now and tells himself that he doesn't love her but yet he still has somethin for her.
If you guys are confused on how to tell what it means then just like actually read the lyrics carefully and slowly that's what I did. =)
