<human>: Can you condense the text into a few key points?

So, I'm dating this girl who's pretty awesome, and we've been together for a year and a couple months.  I have a job, minimum wage, and I pretty much buy her everything.  Food, cigarettes (inb4 smokings bad) groceries, etc.  I have no problem with buying her shit.  Her mother, however, is where issues arise.  She has no Job and can't provide for her children.  She lost her kids to protective services many times, and tonight after we got home she wants me to run down to the store for her to get some things.  No problem, right?  Well, she also has no money.  Additional info: gf has a very low paying job, mother has no job and isn't looking
How can I get her (girlfriend) out of this situation?
<bot>: Girlfriends mom cant afford household needs, has no money and I'm constantly buying them food.  I'm 17.
