Father in law from HELL

Me, my wife and our 1 month old douther are living with my wife parents, and my fother in law came from Hell, i think he is the incarnation from satan himself. I have my own business, i work for 12 hours a day, the payment is fair but i have to pay the credit for company places and i canot aford to buy my own house. like this it will take at least 30 years or more to buy my own house. I just need to get away from my fother in law as fast as possible, if not i will shoot my self because i cant live in hell for much longer. i need to buy my own house.
