My sister and I had a falling out when we were late 30’s early 40’s, because she cut-off my dad and it created a horrible dynamic in the family. My sister and I were never completely cut off from each other, but we went from talking to each other three times a week sometimes for hours to almost nothing for extended periods of time.
Our grandmother died during that time. My grandmother left behind jewelry and some other items that my sister and I split between us, and thank goodness we worked that out like we were the same person. Even after splitting up the items, if one of us wanted to “borrow” an item the other gave it if they weren’t using it. Sometimes we even offer items to the other sister if we haven’t been using it, so it doesn’t just sit in a drawer.
After a few years our aunt became very ill, and we both cared for her.
It’s still not like it used to be, but It’s overall healed.
Being semi-estranged from my sister was pretty awful. Siblings are the people in the world who you know longer than anyone else. Longer than your parents, spouse, or children. That’s typically of course, assuming no one is dying unexpectedly, and assuming siblings aren’t 20 years apart.
Siblings also know what your childhood home was like like no one else. They know what it was like to be a child in your house with your parents, and childhood affects us to some extent in adulthood. Sometimes siblings have very different memories of childhood, but usually it’s not memory of events in the big picture, but rather differing reactions to events by each sibling.
Having siblings for support can be a really great thing. Once parents are elderly or dead, and children are busy being adults, siblings, spouses, and friends are what keep us socialized. However, siblings (family) are the ones who are more likely to be there if you need a place to live or some time or money compared to friends. This is a generalization of course, but I think overall family feels more obligation and more pain to see a family member go through a bad time.
Even estranged siblings often come through for each other in extreme circumstances, but it’s nice if relations are fairly good before the extreme circumstance happens.
I’m 50, and my sister is 2.5 years younger and we still have lots of fun together when together, but there is a little strain here and there when the wrong topics come up. If she died, God forbid, it would be like losing a body part for me. It would be a profound loss.
If you can heal or clear the air with your siblings I usually think it’s worth trying. Of course, it does depend on what has happened. Sometimes things are unforgivable.
