Is he Still with Mai ?

When Mai in the last episode сказал(-а) to Zuko to never ever break up with her again , i feel that by her medium the director wants to say that they will always be together . See Katara is married to Aang, Suki is nowhere, Jin met Zuko once and she is not so important a character to marry Zuko ,left Mai whom Zuko cared for . They will stay together.........thanks
