Is my roommates girlfriend a piece of crap?

She treats me like a piece of garbage even though I pay half of the rent and for all of the electricity, nevermind the free internet I gave them for years until I recently smashed the wireless modem with a hammer. She gets up promptly at 9 am and procedes to plop their 7 month old baby in her baby...chair..thing, directly in front of the tv while she sleeps on the couch until around noon. Meanwhile the puppy that she just HAD to have runs around the house peeing and pooping everywhere because she never takes it outside. She has completely ruined all of my pots and pans from using metal utensils on them (their nonstick) even after I suggested several times that she should use my ortment of plastic spatulas conveniently placed next to the stove. She washes clothes and leaves them in the washer for days...same thing with the dryer. Smoked pot through her whole pregnancy. She's 20 and has no drivers license or job, and no initiative to get either, even though her boyfriend (my roommate) has bought her two (thats right TWO) cars. The sink is always filled with dirty dishes (none of which are mine as I gave up cooking long ago to avoid being around her as much as possible) And as a final insult to me, she takes the access card out of the satellite receiver every time they leave so I can't watch tv...ya know...the tv that I provide the electricity to. (no he doesnt pay for the sattelite hookup, he brought his receiver from his mommys house since there was already a dish here)
