Us Mako lovers need to stick together. The fandom hate is strong. With that being said Asami really needs to break it off with him. Mako is honestly blind to the way he is behaving and he is in denial about his Korra feels. Besides that he is not going to have the balls to end it he is one of the guys that just waits till it gets so miserable the girl can not take it anymore and calls it quits. So Asami...end it.
