I'm looking for the name of a song but I don't know much about it?

It's an R&B sound
It's about a guy who sees a girl crying on her porch over her boyfriend and he asks her whats wrong and he goes on talk about how he would never treat her like that and they end up being close and
then it talks about how she keeps running back to her old boyfriend i think
its not a new song
yea i know its not much
but if you think of anything it would help

its bow wow ft. jagged edge my baby i love that song
