stresses me out!!!

Yesterday I wrote in this forum about the disadvantages of my partner. I heeded the commenter's advice and thought about it all day long. And today i am talking about a problem with finances in my family (my mother is financially illiterate and spends money only on herself). My partner accused me (or not) that as a mother, I am not able to save money and that in the future I will spend only on my wants large sums of money (BUT NO ONE GIVES IT TO ME, so I steal it from my grandparents, for which I am ashamed, but I have no choice, spend it on small things and stand on the opinion that a parent is obliged to provide for children until adulthood). It is impossible to find a job in my area. I realize that soon I will have to save for my wants and spend wisely, but my partner stands his ground. How do I point out this disadvantage in him?????????????
