Lorelai not telling Luke about Christopher

I know Lorelai gets some hate for not telling Luke about her comforting Christopher after his dad died, and although I think she should have told him, I can absolutely understand why she didn’t. Before they started dating she had to go and bail him out of jail for trying to beat up another man’s car because Nicole was cheating on him. And then he tried to fight Dean just for coming to the diner after he and Rory broke up. Point being she’s seen him start to get violent more than once and if I was in her shoes I would definitely be hesitant to say something for fear of how he would react. I know they have a scene where Luke tells Lorelai that it’s fine she had lunch at the Inn with Christopher, but him becoming violent would be more prominent in my mind and might be enough to at least hold off telling him for a while.
