My life sucks

My parents are always arguing (or fighting). I think when they were younger they didn't get much information about marriage,so they don't have a good life together. Unfortunately they have 3 children: me and my brothers. We are unhappy because of this problem.  Some people suggest they split up, but they cannot do this.  First, they are old now, about 45 years old.  Second, we live in an Islamic country and divorced couples are not common. Although luckily these days it's more normal than in the past.
My mother said, "You are young now, so I cannot do it  I'm relaxed and don't pay attention to your father."  But after 30 second forget it.:)
I am going to a dormitory next year. I think this is a good idea because I will be far from my home and my parents.  It's a great chance to taste freedom and find a close friends...I imagine. But now in summer time my life is sucks because of my parents.  Sometimes I think they are like children and have childish behaviors. I wish to god my mother and father would grow up!

Good luck! 

By the way - 45 is not old.......
