i think the video really clears things up. it is all from the guys point of view. he is in love with a girl who doesn't put in the same effort as him and places her job etc over him. "don't you think i knew about all your pretty girlfriends, but i waited for you gave you time to decide," meaning he could have easily dated one of her friends or maybe just another woman in general but he waited for her. finally, the chorus, i think this is him knowing how good of a bf he has been and hes going to find someone else who will appreciate him for that, and the new girl will be singing "here comes my man".
