Having two classes directly reference each other like you described indicates a potential refactoring may be needed. A good book to consider reading is "Pattern Hatching" by John Vlissides; his initial example of designing an OO filesystem abstraction sounds very similar to what your example was trying to solve, only he demonstrates several ways that design can be improved and why those changes are necessary.
