AIW for planning to cut contact with my sister?

I 35M have an older sister 39F. We aren’t close any more and haven’t been in a long time. Mainly because of how she was always favored by our father growing up.

Most times she could do no wrong. We’d clean the house on Saturday’s I’d clean my room, then the den. Before having to help clean her room because it was that messy.

I remember the summer after her freshman year of high school. She had to go to summer school to be able to move up. I had to go help out at the family business to make things fair. Even though I’d done good in school that year.

She would often take my stuff without permission. She and a neighbor girl took a stereo out of my room I’d gotten as a birthday gift one year after I’d just gotten it. Took it outside and put it on my dad’s truck and it fell off while listening to music and dented one of the speakers. My sister was never punished for this.

Another reason I don’t like her is how she treats people. When she first got together with her now husband, he decided certain friends weren’t good enough for her. She cut contact without a thought or care.

She’ll reach out to people if they’ll serve a purpose. Then cut contact once she no longer has a need. Then talk badly about them. Then wants to whine about my nephew having more contacts in his phone than she does.

She treats her own husband and kids badly. She doesn’t work even though there’s nothing stopping her from working while kids are in school. Yet she decides for the most part what they do and what they spend money on.

I avoid spending time with her as much as possible. As I don’t want to be around her better than her attitude.

I keep the peace for now for my mom. Mom has health issues and probably won’t be around in 10 years. I’m seriously considering cutting contact with my sister once our parents pass.
