Sacrificing a friendship for your baby?!

Have any of you mommas had to put your foot down for your baby’s sake/safety? Me and my friend had a play date today with her son (almost 2) my daughter (almost 2). Her son is a absolute demon child. He will hit, kick, bite, scream, throw anything in his reach at anyone around him, bite until his head is shaking and he’s beat red, and steal anything out of my babies hands. He will even hurt himself by banging his head on the walls or concrete…While at her house today, he went up to my daughter out of no where and slapped her right in the face leaving a scratch on her nose. My baby is very shy, quiet, reserved and knows better to not hit or act the way he does. She was very taken off guard and she got upset. My friend blew it off as a “gentle hit” and said “well she didn’t cry she’s okay” 🙃 so after this happened I my daughter was very nervous and scared to be around her son. Every time he came around her she would cry, yell and hide from him. My friend kept telling him to give her space and he got so mad he tried hitting her again and starting biting the siding of the house until he was shaking. After leaving, my friend sent me a whole text apologizing for him being so violent and “moody” and how she was embarrassed, then gave every excuse as to why he acts that way saying “he’s teething” “it’s cause he’s a boy” “he went to his grandparents” “he can sense changes” (cause she’s about to have her 2nd baby) but there’s always an excuse for his behavior likes it’s justified. So I sent her a long text about how I think it’s best to cut off play dates for a while and that I don’t think it’s a good idea for him to come to her birthday party cause the last thing we want is her uncomfortable and scared and hiding and crying on her big day in front of all the family. Not to mention it’s at my MIL house which is super nice and fancy and not baby proofed with stairs and a pool, something bad is bound to happen. I had cut ties a few months before due to his aggressive behavior. This is the 2nd time the babies have been together since then in May…What are your thoughts on my decision? I’m so nervous she will get offended and mad at me 😭 I’m hoping she will understand I just can’t put my baby in a uncomfortable situation…
