I don't believe the person needs to know every thing. In fact as hard as I work on my treatment programs I most likely won't know everything. But I choose to keep going trying to access as many memories good and bad because 12 years ago I chose not to continue trying to remember things. That came back and bit me big time in the form of depression, flashbacks and nightmares 4 years ago which resulted in my locking my son out of the house so that I could jump through a second floor window. I was lucky some part of me didn't want to die and called a friend and my son went for one of the managers. police were called and my son was placed in foster care. my son and I went through a year of invividual counseling, family counseling and I took classes up the you know what. finally he was allowed to come home but the damage for him of watching me go over the edge and the foster care system was done. he came home with reactive attachment disorder, PTSD and a bunch of other things. He will not be coming home again until he is 18. If I had to do it over again I would have remained in therapy and continued fighting to remember what has been repressed. If I had continued working on it I would have known my triggers that sent me into reacting from memories that were burried. Every one has to make their own choices but know with those choices comes consequences. In making a decision like this I think the person needs to know what the possible ramifications of making those decisions could possibly be. In this case years down the road getting triggered and reacting based on a repressed memory. Talk with your therapist so that you can make an informed decision not just a decision possibly based in fear, and stress. take care.
