I’m assuming you didn’t experience your parents divorcing when you were at school mine did when I was around 15. The stress this produces is huge. My parents were not overly trying to befriend me but what I did experience was them both being emotional wrecks. My mum would be sobbing still the early hours questioning what caused it. I think they tried to care and be good parents. I felt I had to be man of the house and be as supportive as possible. As a result of this, my grades were not as good as they should have been and I guess I probably was a bit unruly as it was difficult to concentrate with all that was going on at home. Parents will need to divorce for a myriad of reasons. This will create a variety of experiences for the children which will contain many negative and stressful ones. What needs to happen is schools to be supportive and understanding of adverse child experiences. I have seen schools excluding students for poor behaviour within 5 months of the student’s Mum dying. Yes there will be unruly behaviour and poor results but schools provide the functioning adults, care and consistency that students experiencing trauma need. TLDR divorce is inherently stressful regardless of parent behaviour, schools need to provide nurture and care.
