<human>: I'm currently at university in Plymouth but will be going home shortly. I've only just heard that my step mum and father have split up. They have three young children one is 11 and the other two are below 7yo. I know that having your parents split up can be a stressful time for kids. I mean that i am now old enough to know why they would split up but I am worried that my siblings would not. I was wondering if there was anything I should do? Should I try and talk to them about it or should I leave it to my step mum and father to sort it out. I would like to reassure them as their big brother but I don't know if I should?

Can you give me a shortened version of the text?
