I think I understand the song.
So she has a boyfriend but there's this other guy she have feelings for and she is saying to this guy : 'I had a change of heart and I dont know where to start'. This is about that she want to break up with her current boyfriend, but she don't want to hurt him because she don't deserve him. But she just have to because she just can"t stay away from this other guy ' no matter what its gonna take i've got to make this move you're the one I choose, you know i'm coming for you.. and I just can't go another day without you next to me (this last line proves that she's talking about another guy who isn't YET with her)
