I watched I am Victoria, and so many things resonated with me. I saw a lot of my mother, and other female family members in the character.
To me, it read as an exploration of the belief that hard work delivers success in terms of happiness, wellbeing and supportive relationships, and that deferred gratification is a valid strategy.
Victoria had obviously bought into this belief, only to discover, later in life, that her paradigm of hard work had attracted and, to some extent, created parasitical relationships with other people, namely her sister and husband.
In short, she had worked hard, only to discover she's taken advantage of and not really respected by her family.
Her sister uses her as an atm, with added manipulation, and her husband seems to do bugger all and won't even get up to make a nice breakfast on Saturday morning.
Again, it was an extremely good depiction of a two speed marriage. She wants her daughters to have the things she didn't have, and understands sacrifices have to be made in the here and now, but her husband isn't willing to recognise that reality. He pays lip service to it, but in the moment, he's not willing to let it get in the way.
