He just blinked at her for a minute, sure he hadn't heard what he'd just thought he'd heard. When it finally sank in what she was asking, and that she wasn't joking, he looked at her, horrified and angry. "How dare you? You don't even know him, and you should know me better than to think I'd ever stay with someone who hits me."
He didn't even know what else to say, but if she thought so little of him and his ability to make a decision, then maybe they weren't as good friends as he'd thought.
