Is Jellal really married? Who's his wife? I'm far back and trying to catch up in the series, but as most people confused who are at the same place as me ( On the beach with Jellal and Erza) who really is Jellal's wife?
My friend, you shouldn't ask for things that will produce spoilers. I know the arc that your're referring to and if you really REALLY want to know then reveal the spoiler below. But I would encourage you to just keep watching. 


   Jellal is not married, this is brought to light later. He said that to her to keep his emotions in check so that he could focus on the mission.
