My parents have been fighting a lot lately?

My parents argued before but I have been hearing then fight and I can hear them. They yell and scream. I'm sick of it. I mean they fight and call each other horrible names. My parents won't talk to each other. Then they act all lovey dovey. Parents are so confusing. They fight and can't stand each other and they act all loving. They fight in front of me. My mom said she is glad I saw that because one day this will happen to me and this is real life. They always expose me with this kind of stuff.
