Not all sibling relationships are meant to be mutual and supportive of each other. Not all family's are functional. Not all family's have supportive family members. It's the hard reality of life.

My sister and I grew up emotionally detached from each other. And, later in our 20s I tried to take steps to change that interpersonal dynamic between us, but failed. She is who she is. She will not change.

My sister also does not want to have a real connection to me and is very detached and indifferent to me. She cut me off from her life and her family's life. I only get to talk to her children if I ask to be invited to her house for their birthdays. She has alienated me from our extended cousins on both our parents' families by campaigning against me.

As a result, no one has any interest in staying connected to me through social media or even email. Today, a friend of our mother's and I chatted on the phone randomly b/c I check my mother's FB account to update her friends and former colleagues of her welfare since she is in a nursing home.

Her best friend of 50 years reached out to my mom on FB so I responded and gave her my phone #. She was shocked when I updated her on the severed familial connections I have with my siblings. I know as a result, when she talks to my siblings about our phone conversation today, my siblings will no doubt retaliate with petty gossip about me.

My brother -- a religious zealot who posts about how great God is on his FB account -- physically abused me in our younger years. He and I have been estranged for years. When he tried to reach out through a cousin and my estranged sister to talk to me, I told them both to go to hell. Because neither my sister or cousin like me as both have alienated me from their own familial lives so I have zero contact with them already.

I told them to go to hell, b/c they tried to make me feel bad about their abuse of me. None of them have ever taken responsibility for their own actions against me and they have never apologized to me. Because they don't like or respect me. We're all in our middle-age years too. Much older than you and your sister.

When I told this to my mother's BF of 50 years, she just couldn't believe it. She is herself very religious. I'm a staunch Atheist so I despise religion as its an effective tool people use to hide behind, in order to avoid being held accountable for their own actions against other people.

My siblings "public narrative" or propaganda about our family that they post on their FB, isn't a true reflection of their non-existent relationship with me; it's just what they want people to see. And if those people want to believe my siblings poor opinion of me as being factual, well, I can't do anything about that as much as it may hurt my feelings.

The best advice I can give you to is to research alienated and estranged siblings online. There are so many articles and blogs and other forums that offer really therapeutic and helpful advice on how to transition and adjust to a sibling estrangement.

The worst you can do is to have expectations for her; that she has to meet you where you're at, as far as your expectations. That's the wrong approach. For her own reasons, she has alienated you.

You can reach out to find out the reasons why, but you may not be happy with her answers. And, if you respond defensively as if she's wrong to think or believe what she thinks or believes, you will never be able to repair that broken sibling relationship.

Also, do not involve your parents in this matter. They will not understand and as parents, will try to blame one of you for causing this rift, as they will be unwilling to accept any responsibility for any role they played in why you and your sister have become estranged. So, just leave them out of it.

Do not go to them for advice or emotional support as they will only blame you and offer you their judgmental biased opinions. This is a situation where you need to seek support outside of your family system.
