My step daughter was babysitting my son, he broke his arm, she's being a b****
My son is 5. He was playing with the slide and was trying to hang off the side of the high part of the playground to jump from it to the slide and go down. She saw him do it once and told him to stop or they were leaving. She still didn't get up to be right there. He started to do it again and she got up, grabbed his legs. He wiggled away from her accidentally kicked her in the face and broke his arm when he fell on it.
When I met them at the hospital, she hadn't apologized to him, didn't apologize to me or my husband and said "maybe next time he won't be a brat, not listen and kick me in the face because I told him to stop" and actually said to him "this wouldn't have happened if you'd listened" when he was crying, making him cry harder.
I got mad and said I'd talk to hear when I got home, and she said she'd be at the wedding. I started to get heated and said "you're still going to the f*cking wedding when you put your brother in the hospital??" And she said "he put himself here by acting like a little shithead and not listening" and left. She slept at her boyfriends and didn't come home last night.
I'm lost on how to handle this. I'm furious at her, but dh doesn't want to get involved and she's the type that just brushes it off and doesn't care if you get angry at her. Any advice?
