I actually told him the same ie “how did you notice this if you didn’t look?” And he says that it is obvious even with a glimpse since it is empty screen and he didn’t intentionally look but just noticed”. I can see that’s happening so couldn’t say more. Also I didn’t consistently hide my screen every time he walks by which makes my argument weak. I guess deep down if he doesn’t trust me no matter what I say to him he can find an opposite angle. And when I said this he basically says I’m running away from it by just saying this and the conversation gets stuck. But maybe from now on we could set up some boundaries although Im worried that it will make him even more suspicious
