How is it double standards?
Op is there for her child, her studies are pretty much on the job training, she does get paid for working (a pittance but she does bring in an income).
I don't get this mentality at all. What is OP meant to do?
Live on benefits? Ever tried that, it's not possible. Work for a pittance at a minimum wage job which still would not fully fund a household with a child, so again it would be topped up with benefits.
OP's current plan will give her a chance of a decent quality of life, she will be contributing to society not only thro her taxes but also via her skills as a midwife.
You cannot compare OP to her feckless ex there's a heaven and earth difference between the two.
And honestly for every judgemental post here it must be amazing to live a charmed life of guaranteed incomes.
For me personally when I read the OP the thought but there for the grace of God....came to mind.
It's not easy studying as an adult, it's even less easy studying as an adult with a child and a feckless ex.
OP is amazing, I hope you do amazing and wish you all the best.
