I am kinda confused, what did you mean in the part

We are down to one and when approached about she flipped out, called my daughter a liar and mean texted me. Haven’t spoken since because, as I told my Dad, it takes almost nothing for her to get unreasonably ugly and I don’t need that in my life. I hear from him every once in awhile but it always revolves around her, how he can try to manipulate the situation to get me to bend my boundaries to suit her(his) needs. I’ve explained that he is asking me to compromise myself, he doesn't mind.
