Dad and Mum

Daddy and mummy quarrelled at the coffee shop today. Sis called to inform me and asked me to be back home early. I don't dare to and asked brother to be home early instead. I don't wish to be caught in quarrels anymore. Sis says this time is quite bad and they are thinking of a divorce. This is something they have been talking about since I was young. I hope this is just another time and not take for serious. I just feel like crying. I want to be happy, can I? I don't have much faith in a relationship, I'm trying to work things out and my parents are showing me otherwise. Should I just give up like them?
