That's shitty, I don't know what else to say there.
It's a bit different with her dad because he was the one who was verbally, emotionally, and sometimes physically abusive, some of which still comes through to this day. And he still refuses to acknowledge that he was all these things even after his kids have come forward to him about it (as it wasn't just directed at her but her other siblings as well, especially her brother). To say nothing of him just being a petty, argumentative dick who is just fucking mean about anything and everything. She's cried over that prick more times than I can count in the 15 years I've been with my wife, far more than anyone or anything else, and that's counting random pregnancy related hormonal tears.
