Sounds like she is constantly violating your boundaries. Based on the abusive behavior of the past, it seems like you're also enabling the bad behavior. When dealing with adults, put clear boundaries in place (don't come to my house unannounced, don't scream at my wife, nor come in my home to scream, etc) and if she violates your boundaries, then give her a timeout (she's not allowed to see me/my family/my child for a week).

If it's egregious, you'll need to cut her out permanently. I had to with my mother. (P.S. I've also forgiven her [I hold no grudge towards her and her shitty/abusive decisions throughout my childhood] but...she's still not in my life)
