Hiya, how can you keep piling misery upon misery for Simon. From reading through the chapters all he seems to have is people dumping on him. It's difficult to want to continue reading as there is little happening to Simon that brings any joy to his life.
I know that sometimes life does have a way of pulling the rug from under our feet but to have your main character lead a joyless life there doesn't seem to be any purpose to it, the story that is.
Presumably Simon is living in the 21st century in the UK where there is far more acceptance towards gay people than there was back in the 70s through to the 80s. Yet from reading your story and the way it casts such a downbeat attitude on Simon and his family you'd think that the environment you have placed your characters was somehow stuck in a period when acceptance was nonexistent.
I'm going to read the next chapter but if things don't improve and become more upbeat I'll stop
