Do you have any ideas what could she potentially say?

I'm guessing - one answer would be - let's talk it all over. What should I say 1) I'm done, thansk for this relationship, but I don't want to continue and we have done tanking enough. 2) we talk this over, and it would include saying that her kid is too spoiled (her child offended and hit mine and she did not react, that was a previous concern). I don't want to hurt her even more saying this, I know she would explode and get extremely agressive as her world resolves around her kid. Also I'm resistant to say how hurt I am as it would show how volunerable I am.

I'm also scared that kids will say something about each other when seeing her child. Mine don't want to see hers anymore because her child was hitting mine. She just made excuses to make it ok. It's not ok for me, it's not ok. Even more, I 've seen her hitting her child so I know it's chain reaction. I don't have guts to report her, but I don't want to see her anywhere near me anymore. I just wonder what would the kids say. Would they be offensive. We live close so it's inevitable this situation will happen.

I freeze in conflict situations. She is a fighter. I'm scared
