Lunch once a month- Brianna

Okay so some new shit that i just found out about.
My dad wants to stop paying CS because he doesnt have a job
because he got fired,
cause he went to jail,
cause he beat up his girlfriend right?
right.
So, my mom called their case worker who talked to my dad,
who said he only wants to pay 20 dollars a month.
what do three kids and a parent do with 20 dollars a month?!
Do you realize that once a month hed be buying us lunch?
thats it!
thats all you can do with 20 dollars a month.
anyways, then we found out that he receives $800/month.
and yet he only wants to give us 20?!
like i get it that hes not gonna give us 300 hundred because its not posible for someone to live off of 500 a month, but still.
today i also found out he should be paying $739 a month...
yet when he USED to pay child support he only gave us 300 at the most.
Imagine his bill? first from all those 7 years he never paid, then those 400 from every month he did pay!
idkk... again i state theres a lotta shit going down with this family and im so so soo ready to just let it all go.
