Update to my precedent post

Hey everyone, I don't know if I'm allowed to update my previous post, but oh well, I'll try. A few minutes ago, I finally had the epiphany to talk to my dad about all the things his girlfriend did to me and the fact that he never protected me from it, and also about the fact that I don't dare talk to him because he yells too much, etc... but even though at first it was difficult and he said things like "you're exaggerating," well, he understood that he should have protected me because I was too young, and he apologized and told me that if she says anything to me, I should tell her to get lost. Even though I still want to humiliate this woman, I tell myself that if my dad has realized what's going on, then I won't let her get away with it anymore.
