Here's what Adam and Eddy said:
Quote:
TVLINE | But in your mind what does “get back to her” mean? What does Belle promising, “You’ll find your way back to me again” mean?
KITSIS | As we saw in the Underworld, in these fairy tales there is a life after death. So for us that is what he’s trying to do, he’s trying to find a way to remove the power, to remove the dagger, and to move on with Belle.
HOROWITZ | Their souls should be together, and that’s what he believes.

You can judge for yourself what they were saying, but my 'read' is that their reunion is going to take work beyond Rumple just freeing himself from the Curse of the Dark One and eventually, if not immediately, dying.
All dead souls go to the Underworld, though; it's just that you get stuck there, or did when it was controlled by Hades, if you had "unfinished business" from your mortal existence.
