Arrow - Spoilers galore

Sorry, I didn't think I needed to break it down . i didn't mean are they married, I'm curious why she keeps calling him that. She doesn't really have a sense of humor. They are not together .

Edit: right now story line is dark but in better times I can see him jokingly calling her "honey" or something. Just don't understand it coming from her.

I think it was just her reminding him of the relationship, and obligations to the League. She was drawing from where ever she could to try to get the upper hand in the situation.
