For all the clairvoyants and pagans out there - life after death?

what happens when we die? does reincarnation exist? if we are reincarnated is it true that we have the same circle of people life after life in different roles? how can we find out if someone was our spouse in a past life? does reincarnation have any significance to our current life - are we suppposed to be correcting wrongs from our past life?
