i am the "host" and have been for the past 18 yrs or so---occasionally another will front for awhile.
i have no connection to the past except what memories are shared with me, i have no real "issues" but those "normal" everyday things that arise in a fairly stable marriage or life in general. i can handle all the "big stuff" and have not triggers. nor do i have the degree of emotions that others inside have--or even some on the outside.
i believe i was "created" to raise the sons during their teen years, function in the "adult" world and handle "adult" things.
others front now for periods of time as they work thru their issues from the past.
i don't know who is the "core" if that even matters.
we are learning to work as a team each healing at our own pace, each learning to do a "new" job and create a system that works instead of being so fractured.
now, this is the challenge!!!!
don't know if this helps
