honestly, i get why he wouldn't tell chase right away, especially since there's always a proper timing to things hshs plus, chase seems more visibly anxious for some unknown reason (josh's perspective) so it's even harder to admit it since it "might" add more to his anxiety (josh's perspective though that's definitely not the case) it's hard to admit things to someone that's already anxious for unknown reasons (atleast if left unspoken since we can't pinpoint exactly the root cause of anxiety to people)
I get that and I know you are right, but coming from a person who overthinks every little thing from a past event I get frustrated too. What I think Josh should do is at least ease Chase’s concerns slowly. He doesn’t have to drop everything at once, and I get that Josh is also worried that chase might not accept the idea or hate him if I am making sense?

Joshua I love you, but you are seriously pissing me off right now.. Just let this guy rest and tell him everything
