And Here I Am Fighting Fighting Yes I'm Fighting not to cry And that's another reason Why I oughtta hate you like I do Like I do

from those lines i think that shes the reason he's leaving coz they got to close for comfort, like he realy likes her, but he has commitment issues.

and his fighting not to cry because he dosent want to leave her, but its a good reason for him to hate her coz she shouldnt mean so much to him to make him want to cry. then he repeats 'like i do' because he dosent fully believe it so he repeats it to convince himself.

just guessing, what do ya think?
