I am cutting my sister out of my life finally. We never had a great relationship growing up because we were?

Me and my sister havent really spoken in Two years and have had a rocky relationship our whole lifes. And Even though I do miss having her in my life it is alot easier without her theatrics and the costant drama she stirred up. On sunday I did stop bu her super bowl party it was the first time we have even been in the same room in probably 8 months and let me tell you there wasnt any pressure and it was a lot better for both of us to not have to pretend to like each other . I would even say I had a good time.
