Horrid in laws

Looking for others to make me feel better lol I always thought I was so lucky to have amazing in laws. My husbands family is awesome and truly make me feel like part of the family. However: my sister in law on my side is so awful! I cannot even begin to describe all the horrible things she has done to myself and my family since coming into our lives. I'm at the end of my rope and I can't handle it any more! I hate to call other women this but she's such a bitch. I don't understand how my brother allows her to treat us all and him the way she does. There is no way in hell I would allow my partner to be so disrespectful and downright mean to my family. She's constantly in competition with me and I don't know why. Thankfully in the last little while my family has now caught on to her antics/bullshit, or rather couldn't ignore it any longer. But still. I'm so frustrated. I just want to scream at her. Get out of my life crazy bitch! It's especially frustrating because I only surround myself with good people. Good friends etc I don't tolerate this type of bullshit and I choose not to have it in my life. Life is too short to not be happy. But I can't get her out of my life. Arrrrgh!!
