Trying to support my daughter who left an abusive relationship

My daughter was upset because her brother which is my son has cut her off. My son is 17 and doesn't want anything to do with her and went to his dads for Christmas. My daughter was in a very toxic and abusive relationship and I have tried to validate her feelings after leaving. I also explained to my son how hurt people hurt people because she took a lot of her anger out on us. They stopped talking after she got mad at him for accidentally spilling something in her car and she kicked him out her car and left him on the highway. She hasn't really apologized. She mainly expects everyone to forgive her for how she treated them because she was being abused. I forgive her because she's my daughter. I'm trying to support her but she doesn't seem to understand that just because you were going through something doesn't mean people have to forgive how you've treated them. She keeps feeling entitled to people's forgiveness when she hasn't given any apologies.
