Sister is a selfish nasty person, how are we related??

[Kingk1]

Needing advice as my selfish sister says I'm overreacting and emotional. Visited my sister Christmas '17, booked flights hotel and was looking forward to seeing my family. Two weeks before we were due to fly the hotel cancelled my booking and the only other hotel available was a very basic hotel at side of motorway (10 minutes drive from my sister). My DH (2 x DS) and I were thinking of hiring a car due to the location of hotel but my sister said not to bother as she will collect us and drop us back in evening, the hotel was just for sleeping in. She had arranged days out and nights out catching up with friends and family. She collected us from airport and we didn't see her until the next day. She was meant to come back to hotel later for dinner and meet up with family and she never turned up. She said she was tired and had an early night. The next day activitie she said she had organised she didn't, the people she said we're coming knew nothing about it. She met up with us the following evening and that was it. We stayed in hotel for 4 nights and saw her for 1 day Christmas and 1 of the evenings. She never even called into hotel to say goodbye instead she visited a friend on our last day and actually drove by hotel. I am so hurt and angry as she said she had all these fabulous events organised, meeting up with people etc and she organised nothing. When I rang friends to meet up alot had plans already made with it been Christmas time and they were disappointed that I had left it till last minute to let them know I was over, but my sister told me she had been in touch with them. When she visited me she stayed with me and I brought her out and we had a great time together. When I returned home I told her how upset and angry I was. The holiday coated me a fortune with having to pay for taxis etc when I could hve hired a car. She said she has nothing to apologise for and I should get over it! It's been a year since I have spoken to her, I do miss her but she has always been selfish person and constantly tells lies this is just 1 of alot of shit she has done to me over the years that I feel enough is enough! Do I just accept that she a selfish person or keep away? TBH I am enjoying not having her shit and constant lies in my life! Sorry for the long post :)

Tbh the fact that you're enjoying your time without her in your life says everything. It doesn't sound like she really adds any value to your life.

She sounds a little unhinged tbh. She just flat out lied. She created a delusion of reality and then told you to get over it. Not normal.

Did you enjoy her company when she came to stay with you? Would she help you out in an emergency?

Obviously you will want to see those family and friends again, so next time speak to them direct, make your arrangements and leave her out of the loop. She isn't worth it and she'll only let you down again. Go LC.

I think it's up to you but if you see her you will just have to tale everything she says with a pinch of salt and assume it's a lie

If she has form and lies then you shouldn't have relied on her to sort out your holiday. Let that be a lesson. You should have contacted friends directly to make arrangements.

It sounds as if she won't change, but you have to decide if you miss her enough to accept always being the grown up and reading between the lines/lies.
