I agree with the last posts, but I feel like she uses double standards for each of her parents. She behaves like she's got nothing to do with her father's bad behaviour as a husband but judges her mother for leaving him. Not implying it has to do with the support she gets from him, but the way OP puts it makes me see think the daughter is being unfair.

Anyway, I would never, ever measure my parents for what they buy/give me . My mother also becomes bitter because of that sometimes and I can't convince her she's a good mom, but the truth is it isn't a competition and there's absolutely no need to behave as if it was.
