<human>: Condense the text into a few key points

My mom and dad argue every Saturday each two weeks. This the time which my dad starts drinking a lot in the house . When he comes from his friends house they both start talking about leaving each other due to their issues.

My dad also likes to flirt with other girls in front of my mom. During the argument he says he's the boss and he owns my mom since she lives with him in his house. He turns into a big bully and those what ever he wants and tells everyone what to do. He tells me advice that all girls are not worth it and to just go to college.

My mom gets really angry for little things we do so when my dad drinks she gets really mad.(Examples: ) She turns 180 (or is it 360) in a a few second of being happy to angry. She talks about finding a new apartment and leaving. 

They make me join the conversation by asking me questions who I want to go with. I don't answer and tell them i didn't hear them because  I was distracted by the TV or something. I don't answer because i'm afraid if i do they will really leave each other. My borhter(M12) is mostly in his room playing and is not usually included in the conversation due to his age.

They argue mostly when my dad drinks and even on rarely then he is sober.(That means not drink right?) the only other time they argue is when its about paying bills or sport bets, but they don't get to this extreme.

I get really depressed when they do this. I don't say anything and try not to cry, so i just distract myself by playing a game or seeing a funny video.  The only reason they are together in the first place is because of my being accidental. They had me when they were in high school. Sometimes i wish i wasn't born so they both could be happy and be successful.
