<human>: I'm currently 17. I lived with my dad my entire life. My mom died in 2009 and I began receiving social security checks every month for about $600. In November (2010) part of our house burnt down and we got an insurance check for around $20,000. 

Now, my dad is not a poor guy. He makes about $30 an hour full time, and has a girlfriend who works full time as well. However, he always tells me how "broke" he is, and how he can't afford anything. I think this is complete bull shit. He shops at the expensive grocery store, always eats out, and buys himself expensive toys like motorcycles. And he is not in any debt. 

A few months ago I began to ask him about the social security check and the insurance money. He told me that he was able to take care of me financially (as in buying food, health insurance, etc.), but the only thing he can't afford is my car insurance. So basically, he's saying that the only part of my social security check that is being used on me is for car insurance. So where the hell is the rest of the $600 going? He doesn't even pay for my phone bill, gas, or clothes. This I have to pay for myself, even though I have no income. Actually, he did buy me a HALF tank of gas once. But his girlfriend told him not to do that anymore. I feel like she's in on this too. 

 As for the insurance money, we got the check in about January and I have not seen a cent of it. I believe I lost about $700 worth of stuff in the fire, and only one thing has been replaced. He agreed to buy me a new computer instead of giving me money, which I agreed to.  NOW, he's saying I need to give him $300 and then he will buy me a computer. 

Then my cat got sick. The bill was around $600 and now he's saying that I need to pay him. (My cat is still living with him, unfortunately.)

Our relationship has been particularly rocky lately. But

Can you condense the text into a few key points?
<bot>: he hit me and I moved out (about a month and a half ago). I'm now living with my grandmother. I believe he gives her about $100-200 for food a month.
