My horrible sister in law.

My sister in law is an extremely toxic person. She’s always been manipulative and calculating. A few years ago she threatened to keep my nieces away from myself and my parents because I wouldn’t give her 6 year old a bandaid. The reason I wouldn’t was that not 5 minutes before I gave her a bandaid and she peeled it off so I told her she didn’t need another one right now. My niece cried and my sister in law decided that was grounds for cutting us off. We were able to make amends but have walked on eggshells around her ever since. We are constantly worrying that she will wake up one day and decide we can’t see our precious nieces again. It’s been awful. Well today is my birthday and my youngest niece who is 4 FaceTimed me. They had been out of town so we were all chatting about their weekend and she was getting all excited for my little boy who is getting his big boy bed today and we are putting it together. The 2 of them were getting so excited for each other it was the sweetest thing. And then my sister in law comes in the room screaming at them, like absolutely screaming because she told them not to call me. I didn’t even know what to do or say, I just stopped talking because I was afraid she’d rage even more if she knew I’d heard her. Shes never physical with them but she very much yells and screams a lot and I’ve never heard her scream like that. My oldest niece hurried and said love you, talk later and hung up. I’m heartbroken. I don’t want them to be afraid to call me. I want them to know how much I love them and that they can always come to me. My husbands own family is super toxic and everyone else has sided with his parents who are horrible and think we’re in the wrong for keeping our distance because they can’t see past the “perfect” family facade they’ve created so he has no one and I don’t want her girls to feel that way ever. I try so hard not to do anything she may see as undermining her but we were just talking. They were so sweet and then they looked so upset when she started screaming. I wish my brother had never married her.
