Search Results: hating boys

My older sister never seems to be happy for me when something good happens in my life and she gets low key jealous when people around us start complimenting me about anything from looks, career or love interests.
People have approached me to ask me why does my sister hate me so much. These people are neighbors, church members and family friends. She pretends that she is such a great sister to me in front of my brothers and our parents so they can continue to laud what a wonderful sister she is to her younger siblings.
Some of things she has done were: Ruin my babyshower by using it as a rivalry with her ex bestfriend. By the time that shower ended, my family was divided and my aunt and my cousins didn't speak to us for over 5 years. She lied to everyone including my niece at her sweet 16 saying that she didn't know where I was when all along I was waiting for the ride she promised she'd send for me. My niece balled her eyes out the entire night thinking I flacked on her.
There's so much more but it would be way too long to write down. She's toxic and brings me nothing but negativity and stress to my home. She offers no support whatsoever and it feels like she only wants to sabotage me any chance she gets. She has told me to my face that I am not her sister 3x. When I tell my parents what she does, they say that I am acting this way because of my husband and they accuse me of being boy crazy for putting him first before family. This infuriates me! She's toxic! I feel its time to cut her out of my life. Ain't no way in hell would I have let her stick around this long if she was a friend and not my sister. Am I wrong if I do? Would you so the same? I feel like if I keep her around she's gonna betray me so bad that I may flip out on her.
