The User Relationships API:

The module also invokes a "user_relationships" hook passing in the following arguments:
  $type will be a string of the following
    $type     | $category               | Description
    ----------------------------------------------------------------------
    insert    | type                    | before a new relationship type is created
    update    | type                    | before a relationship type is updated
    delete    | type                    | after a relationship type is deleted
    load      | type                    | after a relationship type is loaded (so you can add data to it if you'd like)

    load      | NULL                    | after a relationship is loaded
    pre-save  | request|update|approve  | before a new relationship is created, updated or approved
    post-save | request|update|approve  | after a new relationship is created, updated or approved
    delete    | remove                  | when a relationship is removed
    delete    | cancel                  | when a relationship request is cancelled
    delete    | disapprove              | when a relationship request is disapprove
    

  $relationship either the relationship_type or relationship object
