1. You may still need to feel some stuff about your parent's divorce and the past.
Before you can step out of your old role in the family you may need to
    grieve the past and, no, understanding it isn't the same as feeling
    it.  You may be in your 40's or 50's but still feel hurt or mad at unconscious levels about the split up of your family. 
    2. You may need to set some limits.  
If you have been the emotional caretaker for siblings or parents
    then you may need to just say "no" in order to de-role.  Examples of
    how this might show up is often times younger siblings can "parentify"
    their oldest sibling and cast them in the roll of parent whom they
    may cling to or act out with in similar fashion a child or teen
    might with a parent.   Cute, maybe when you are 7 or 10 - not so
    cute when you are 50 and your sibling still looks to you to plan all
    the family gatherings as if they are incapable or is indifferent to
    you when you visit the way a teenager might dismiss their parent. 
    The same goes with parental care taking - you may become, inadvertently the
    surrogate mate or confidant for your parent - especially the
    opposite sex parent who is not re married.   Setting limits may not
    always have to be verbal and confrontational and sometimes they may
    need to be.  See Ali Miller's posts on 
Non Violent Communication for
    more.  In the cases where parent or sibling relationships are
    tense, there is value going in with a clear understanding, as a
    friend recently said, of what you are available for?  "I am
    available to listen, to love you, to tell the truth, to share the
    planning tasks, to hang out" and "I am not available to be dismissed,
    parentified, treated disrespectfully".  Just setting the intention
    may shift your role and at other times you may actually have to say
    this stuff and weather the tantrums that may ensue from family members who don't like you stepping out of the old role.
    3. Plan ahead for self care.
Don't over do it in your visit.  You want to be your authentic,
    grown up self, not the child who took on various roles in the
    family.  But to stay in that head space it is important to have
    moments built into your day where you can check in with young
    feelings that may come up and need tending.  Listen and hear what
    the little one inside of you is feeling and needing.  Often these
    feelings have been dormant until you are around your family and then
    the unconscious stirs.  The pesky unconscious, I have found, can
    often reveal itself in messy ways and at inopportune times.  So have
    a place you can go to take care of yourself.  I recommend you do not
    stay at any one family member's house.  You need your own space to
    refresh and you need time to set aside to do it.  You may also need
    to plan ahead for other logistics - set exact dates and times and
    activities.  If you are visiting two
    separate sets of family- a mother and new partner or father and new
    partner or brothers and sisters - set it all up ahead of time.  Even
    if you are like me and aren't a planner, it can make a big
    difference in keeping your feet on the ground and sense of
    authenticity intact.
    4. Mind your longings.
If you have lived through one or many divorces as a kid, you may
    still carry many longings with you into your current family
    relationships and many/most of these longings are misplaced if you
    expect them to be met with this particular group of people.  You may
    long for family to comfort your old grief or celebrate the adult you
    have become or you may long for a stoic parent to be touchy-feely or
    an invasive parent to be more hands off.  The reality is, and you
    have heard this before, we have control over ourselves and our
    choices and not others.   Choosing to get certain longings met in a riper garden for you and not with a family that is still stuck
    in old splintered roles might be a better bet.  You may not be
    valued for your depth, emotions, view on life, work, politics, or
    relationships.   Take those aspects of you, then, where they are
    valued and enjoy the other aspects of your family.  They are there,
    I promise, if you can let go of the expectations that are
    unmeetable.
    5. Empathize with and accept yourself and your family.
I am going to get a little positive psychology on you here for a
    minute not to Polly Anna-out at all but simply to embrace the larger
    context.  You can read my 
previous post on blaming your family for
    all your problems for more on this.  Bottom line, family is fraught
    with the deepest longings and most primitive animal instincts and so
    with it comes the potential for great joy and great pain.  In the
    midst of that we are navigating a culture that is valuing less and
    less deep human connection.  Throw in many generations of family
    history that have left its mark on parents and their capacity to
    parent kids through their emotional lives and you can see that no
    one is to blame and everyone is to blame.  We all get to be angry
    and sad, say yes and no to our family and beyond that we also get to
    empathize and accept that this is the family we have.  The best
    thing about being an adult is you get to choose how to engage as a
    member of your family.  Enjoy the freedom!
Finally, for those of you who have lived through divorce and had parents parent you well and have come out on the other side better off for the experience, perhaps this blog gives you a new sense of gratitude for them! Divorce does not have to be the end of the world for kids but kids are not alright going through it without guidance.
