I think I large part of the reason she hates her dad is because he doesn’t put up with her shite and she doesn’t like it. Whereas Jane (I think) likes feeling needed by her. I know some of it is tied up in her dad’s coming out later in life and we don’t really know the back story to that (again, I think) but given that she is also a part of the LGBTQ+ community, I’ve often wondered what it is about their relationship that so broken. I really do think it’s simply just that he tells her no and gives her a reality check especially as Jane and he still live together and I assume have a good relationship still?
Without a doubt she has some mental health issues but I also think she’s just not a very nice person either and so when people are upfront with her it create drama. Look how intense her friendships are and then they break down, I bet a lot of that is down to closeness being created very quickly then her being offended when the other person is honest with her. Then she cuts them off.
