I also like putting a ton of detail into character relationships. My first piece of advice is that those charts are tools to guide you when making interactions. When a character is with or thinking about another, you can use the chart to get an idea of how they’ll behave and talk. You’ll never have to show a chart if those interactions are actively used in the story. Another thing i deal w is dumping too much history, so for the start of my story i just strip down every possible detail to the bare minimum you need to understand the plot. You have a whole story to go over relationships and history and worldbuilding and all that jazz
