His head snapped over to her when she spoke, frowning deeply. That was... not what he was expecting. She was breaking up with him!? Again, he felt extremely angry.
"You want to take a break," he said, looking away from her, glaring toward the wall now. "You mean you want more time to snog this mystery bloke of yours." Best mates his arse. She couldn't even tell him who this bloke was. Why? It certainly was obvious now. "So go be dizzy and hopeless with your fucking mystery man." Of course, that wasn't at all what she said, but he hardly heard her right now. A 'break' never meant what it was technically supposed to mean. She wanted to break up and he'd be damned if she'd do it first. "Fine. Go ahead. I'm just a hindrance. If there's no fucking sparks there's no need to continue if you have sparks with some other bloke who's obviously enough to get you to try and shag him."
With that said, he pushed himself off the wall fully ready to storm off. He definitely realized that this was rather close to a temper tantrum, but he didn't care. He was exceedingly angry and there was no amount of reason that could get him to think anything other than he thought at the moment. If she wanted him to be civil again she would just have to wait for a good long while.
