Dean was not entirely sure what was happening. Well, that wasn't entirely true - he had a fairly solid assumption about what was about to happen, but he didn't understand why. Sure, things had been a bit off, lately, but he hadn't actually done anything, had he? He didn't think he had, not for a while. The last time he'd upset her, as far as he knew, was Andy's Birthday party thing... Which, okay, they still hadn't really talked about, so maybe she was just more upset about it than he'd realized.
Maybe she was just done.
He didn't really know how to do relationships - hell, the fact this had lasted as long as it had was a shocking accomplishment. He should just be glad it had worked for as long as it had, right? If she was done, he wasn't going to argue, even if he wanted to.
Since her messages, he'd started fidgeting. Pacing, wandering room to room picking things up and setting them back down. He wanted to drive, it was that brand of restlessness that always made him take off for an hour or so, but right now he couldn't - she'd be here any minute, and if she showed up and he was gone, she'd probably be even more upset. Rightfully so. So he couldn't drive, which left fidgeting.
The sound of the door closing, and the quiet sound of Jules' voice sent him out to the front of the apartment, and he probably looked sort of like an over=sized kid, peeking in the room like he expected a scolding, offering a tentative smile like that would maybe dissolve whatever made her upset. He hesitated in the doorway for just a second, then crossed the room to where she was. "Hi."
