I Don't Want You to Not Be My Husband (слэш)

Sirius knows that he's the one to blame, just as well as Remus does. He watches the pen lift and drop, arcing smoothly down towards the paper . . .
"Stop." The word spills from Sirius' lips, louder than he'd intended for it to, and he realises he's standing up.
Remus blinks, and looks up at him. "Stop?" he asks quizically. "You're the one who asked for this. Isn't this what you wanted?"
Sirius' chest is heaving, and he clutches onto the table. "I don't know," he says, panicking.
Remus sets the pen down. "You don't know?" he repeats scathingly.
He's hurt, and Sirius knows he has every right to be.
"I don't want you to not be my husband." He forces the words out, even though they tear at him inside.
"You haven't been a very good husband, lately," Remus says at last, and Sirius is horrified to see tears glistening around his lashes.
