It's almost worse, her trying to placate him. It just confirms his suspiscions that he was rubbish. And it's not like he can do what he would with another woman, namely, throw her out. Hell, he doesn't even want her to leave.

By the end of the cigarette, he's come to the conclusion he can sulk or he can do it again and prove to her that he's good. One choice means no sex, the other means a lot of sex.

...it'll probably come as no surprise to anyone that after stubbing the smoke out, he turns his head and kisses her gently.

'I know. We're going to use it too.'

All. Damn. Night.
