I've seen first hand what real abusive parents are. I'm sure some teens will find their dads lover ignoring them to be a form of child abuse I just happen to disagree.
I've encountered far worse in my life... I am not saying this is egregious just that it isn't exactly benign. Truth is we have no idea what age the MC was when it started and the extent of the "ignoring". Ignoring a child or young teen who is injured, sick, or in anyway in pain/needing medical attention can be considered neglect. We don't know that the MC was ever in a situation like that so it makes no sense to assume that she did ignore something of that nature. Just pointing out that "ignoring" a person can be harmful.I've already done this dance with you and you know my theory. I don't think she will end up being the villian in this story. I've said I could be wrong, but that's the way I'm leaning. As far as ignoring and avoiding equaling abuse sorry that's going way to far. Most teenagers are not trying to spend any time with their family anyway. He was fed and looked after not tied up in the basement and beaten. I wouldn't even go as far as to call it neglect. It certainly wouldn't meet the legal standard for charging them with neglect. He wasn't loved by her, but she wasn't his mother so not really a crime. You can say mistreated to a point, and I'm certainly not pretending she was a saint. She was not good to him that doesn't make her a demon.
The truth is there are so many people the MC can choose from in this game that I see no reason for him to be interested in any overtures towards repairing their "relationship" (if they can really be said to have one). I don't see a reason for the MC to trust her, in that nothing she has done so far makes her really trustworthy, which is the entire nature of the story. We are supposed to doubt everyone until the final reveal of the will. Of the MILF characters I just find Elaine the least worthy of the MC's time. Obviously, just my opinion.
