no offense, but its a little annoying how people come on to say how they like a song but dont try to interpret the song. isnt that what this sites for??
my interp:
its either about some guy bein cheated on... and hes basically saying: if i cant make u happy anymore, just dont be with me.
you cant persuade me to stay now.
or maybe its a person who was a close friend who fell for the other saying, "i cant help you to choose what you should do anymore... i thought i won you over but i lost you"
idk ... seems right to me... either one works fine for me but theyre probably not right because its like 2 different things in different parts of the song... but then again the lover could say, "i supported you this whole time and now i wont, i thought i had you, but i guess not"...idk if that makes too much sense ...oh well lol
