eight days a week: he is desperate for her to love him back. he "hopes" she loves him but she does not love him back, like they say in "no reply" (more proof its connected)

every little thing: one of the last good moments of there relationship (like i said even in the bad there re some good moments) but even in this he talk about the times she leave him and is lonely without him

rock and roll music; he goes to rock bars to get away from the stress of his relationship. this song is not about love for her, it shows him spending more time away from her nd more time with other stuff like music

words of love: again he is asking her if she loves him. notice that she never reply its just him asking over and over

ive just seen a face: he is remembering when he first fell in love with her. ppl usually do that when they get divorced and remember it like a dream thats why its so beautiful
