I'll wait for you
I believe it is love that is waiting for him. It's cool to listen to the song as if it is love writing a song to you.
For instance in the chorus it says 4 will not wait for 3 for 3 never waited for 2. 4 is the girl he likes that wont wait for him. 3 is him and 2 is the girl that he never waited for.
4 and 2 are his new and old "lovers" and he wants to wait for a specific person but instead he should just wait for love and not a specific person. Love is telling him that although he will not wait for love, love will wait for him. I'm not exactly positive this is the meaning, but it makes the song really interesting when listening to it with this perspective.
