He sticks around and supports her despite her being herself and treating him less than stellar in many an instance. He *understands* that she doesn't really mean it, that she really does like him, without forcing her to say it all the time or change her behavior.

On the other hand, he's not afraid to fight back. In Season 1 and 2 he doesn't cower from her, he yells back in her face, when she insults him. In Season 3 and 4 he's learned her game and they're practically on equal footing. iPWV had really good examples of this.

Those are the two big reasons I see. Then other little stuff, like she likes his personality, including the techy stuff. They have similar sense of humor a lot of the time and its easy to get on with him when its just the two of them. He SURPRISES her a lot, which I think is a big thing, and he's done some things that really impress her. And I suppose she doesn't dislike his looks either :P
