From what I understand, the point isn't just to relate the memories. The point is to take those memories and attach different meaning to them.
To begin with, as my T keeps saying, that they are MEMORIES, which means they are something that happened, "over there, back then", rather than something that's happening now.
The memories of things "done TO you" tend to be associated with thoughts of being powerless, helpless and somehow at fault, guilt, responsibility, etc.By revisiting those memories, safely, in the present, when you are NOT weak and powerless, it can be possible to come to accept that you WEREN'T responsible and to put the guilt and blame where it really belongs. At least that's the theory, as I understand it right now. This is sort of a work in progress, so no promises that I've got it 100% right.
The other thing that I've found, for myself, I tend to think "If people knew the truth, they'd hate me." Or maybe a more complicated version of that. Once or twice, I've taken a chance on that and said something to someone that I REALLY thought I could trust. To my complete surprise, he didn't hate me. Didn't change out relationship at all..I had no real idea that was possible. Turns out it is. That's worth knowing, I think.
But none of that is the same as pressuring someone to talk about stuff they just aren't ready to talk about yet, just for the sake of talking about it.
