Ok, let's look at it through my logic
Let's take my current financial situation and compare it to that woman's financial situation. Only, I don't take welfare money, my boyfriend takes care of the bulk of the financial burden, while I supplement only the food. I work part-time at a restaurant (because I can't currently find a better job since my Swedish sucks) and I save the rest of my money for 'the rainy day' - for both of us.
So, let's say he makes about 3.5 times more than I do, therefore he pays the rent, utilities and for food when we go out (which is about once a month at this point. Upon agreement, I pay for groceries and cover my own individual expenses (bus card, clothes, etc.)
If I went out and bought myself a pair of Dolce Gabbana shoes that I don't need, do you think he'd have a say about it since it really is 'his' money that I'm spending (even though it's techincally mine, but we pool it and he pays all the bills, etc.)? Do you think he'd be happy about it since we are glad we have enough for food, bills and maybe a little on the side for entertainment/clothes? Shouldn't I just stick to buying stuff we need - or I need.
That's the rationale. The state is the boyfriend and the woman is me. If I started smoking right now, my boyfriend would get royally upset with me because it would be DISRESPECTFUL and INCONSIDERATE of me and he'd request that I stop immediately. Also, if I decided to go out and party like it's 1999, I'm pretty sure he'd have a say about that too. And I get on his ass about spending too much as well as we're expecting a family now, but that's beside the point.
Just a little bit of perspective ...
