Just make a relationship from Project to it's self for each

So does the inverse relationship not matter in this situation?

The inverse of 'north' is 'south' etc...
That's assuming that you're dealing with a model where that's the
case. If the original poster is trying to construct a game where -
for example - you may have one-way doors or mazes of twisty passages
(all alike), then the "exits to" relationship probably doesn't need
an inverse. The exception might be in a graphical editor, where it
might be useful to know what links exist to a given room.
