Mine Is By Far the Worst Sister In Law Ever!
I have been married 25 years and we no longer have contact with my sister in law. She has never liked me and has said so over and over that I am not good enough for my husband. She has done everything in her power to destroy our marriage. She even went as far as to try and have sex with my husband in front of me. I still have images of her naked ugly, fat dimply thighs and saggy breasts rubbing up against my husband while she groped at his crouch!
She was extremely mean to our kids pinching and poking them leaving them black and blue. Whispering nasty things to them when she thought no one was looking.
She is 54 and has never married and cannot maintain a relationship. We actually moved continents to get away from her poison. It was the best thing we ever did.
