Something that has been bugging me since I had the chance to take the Ceremony of Eternal Bonding is that when Heavensward is introduced, will I still be Eternally Bound to my partner even if they do not necessarily go into Heavensward and vice versa?

Because I want to take a break from FFXIV before getting Heavensward and I want to be sure that when I am ready to rejoin the game in Heavensward I will still have the Eternal Bond that I have gained with my partner and that it will not be lost.
