user13520: If the self is an illusion - of little importance - where does that leave my relationships?
All the people I know, have a relationship with this 'fake self' of mine -- so the relationships are groundless? an illusion also?

user471: Your relationships are simply conditioned and impermanent. Even your closest relationships may be subject to death, disputes and drifting away.
The Buddha praised admirable companionships in SN 45.2:

As he was sitting there, Ven. Ananda said to the Blessed One, "This is
  half of the holy life, lord: admirable friendship, admirable
  companionship, admirable camaraderie."
"Don't say that, Ananda. Don't say that. Admirable friendship,
  admirable companionship, admirable camaraderie is actually the whole
  of the holy life. When a monk has admirable people as friends,
  companions, & comrades, he can be expected to develop & pursue the
  noble eightfold path.


user6994: The person is not an illusion, it is like an illusion. It is like an illusion in that it does not appear the way it exists.
An illusory horse appears as if it was an actual horse while it is not. From a Prasangika viewpoint, similarly, persons and phenomena (such as relationships) appear as if they were inherently existent while they are not. In this respect, the person is like an illusion.
In a commentary to Je Tsongkhapa's middle-length Lam Rim, Geshe Gyaltsen says:

One will come to perceive the person as like an illusion when one has
  realized emptiness. Therefore one will know the illusory aspect of the
  person in that the person appears as truly existent, but does not
  exist as such.


user111: You are asking something like "If superman is fictional, what happens to his relationship with Lois Lane?".
In ultimate reality, relationships don't exit. It's just craving/clinging arising in the mind for seeing, hearing, smelling, touching etc.
