Input: My sister and I have a complicated history.  We come from a divorced family and both of our parents have passed away in the last ten years (we are both in our 30s, so our parents did both pass away rather young.)

My sister and I have constantly bickered throughout our lives, and I know that she harbors resentment towards me due to the unique arrangement that was reached between our parents after the divorce.  My father moved back in with his parents after the divorce and I moved in with him shortly afterwards, while my sister stayed with our mother.  Soon after this, my grandfather passed away from cancer and my father remained by my grandmother's side to take care of her.  In essence, I was raised by my father and grandmother and only occasionally visited my mother.

My sister definitely got the short end of the stick.  Our mother was an alcoholic and a drug abuser (prescription medicines mostly, but more illicit substances here and there for sure) and had terrible choice in men.  My sister was placed in an emotionally abusive situation for her entire childhood and it messed her up quite a bit.

Once we grew up, my sister moved in with her boyfriend in her early 20s and eventually they had two children together.  I was a bit of a later bloomer and didn't really get my life together until my early 30s.

When I was about to be married is when things really started to go south in my relationship with my sister.  My wife and I had decided to have a small ceremony but had of course invited her.  With less than a month to go before the wedding, she had not RSVP'd and when we spoke about it, she was offended that my wife had not asked her to throw her a bridal shower and also that her son and daughter would not be the flower girl and ring-bearer. a) My wife did not want to ask anyone to throw her a bridal shower.  Her aunts offered to throw her one and she accepted.  My wife would have been happy to have a bridal shower thrown by my sister, but did not want to solicit one herself. b) As previously mentioned, we were having a small ceremony and did not plan to have a ring bearer or a flower girl.  We only had one person each, a best man and a maid of honor.  I explained to her that it wasn't going to be that kind of wedding.

Eventually she did decide to go to the wedding, but it was like pulling teeth and she made up some story about "not getting the invitation" (this will be important later).  The wedding was lovely and the next couple years were fine.

At Christmastime of last year, my sister stopped talking with our grandmother over an argument they had on Christmas Eve.  My sister had not brought a gift for my grandmother (although her children had brought grandma a gift.  My grandmother, being a fiesty 90-year-old woman, made a comment about it, so my sister went from 0 to 60, grabbed her children and left.  She did not speak to my grandmother until this September and would not return phone calls and messages on the subject.

She also cancelled family get-togethers (namely her children's birthday parties) this year and has generally been difficult to reach.  My wife and I attempted to reach out several time, but were ignored or given the run-around.

Things came to a head earlier this year when my wife and I became pregnant.  My sister was one of the first people we tried to call, and we left a few voice messages on the subject.  We didn't outright say the news, but we ended the messages with "call us back, we have some really exciting news to share!" each time.  As a couple of childbearing age that had been married nearly two years at the time, we felt like we were laying it on pretty thick with the messages.

The messages went unheeded, so we stopped trying to give my sister any special treatment.  We had stopped communicating over text for a while, and, as mentioned before she seemed to be intentionally making herself hard to reach.

My sister found out about the pregnancy a few months later when it was safe to post on social media.  She sent my an angry text message that day about not telling her.  I simply told her that she was one of the first people we tried to call and that we had called several times.  She claimed to have not received those messages (sensing a pattern yet?) and tried to make me feel guilty by bringing up that we never talked to her kids anymore.  We would have been more than happy to visit with her children if she did not make herself so difficult to get in touch with, if she didn't stop coming to family functions and cancel traditional times where we would typically see each other.  We eventually stopped trying after every conversation either became a runaround or an argument.  At this point we felt that the relationship had become toxic and started ignoring her.

Despite this, I insisted that she be invited to our baby shower.  She was the only person who did not RSVP one way or another (she must not have gotten the invitation again) and did not show up.

She has occasionally posted on social media, lamenting the fact that she does not have a close relationship with her remaining family, and makes herself out to be the victim and the rest of us villains.  Hence this thread.  Are we the villains?  You are clearly only getting one side of the story, but should we have tried harder after getting ignored repeatedly?  Are we privileged assholes who don't care about our extended family?
