Jayce is the one who insists they're best friends, aiden only called him a friend. its obviously not the first time jayce has done something like that too AND he had zero remorse. its not aidens responsibility to work things out because he didnt do anything wrong.
whats the point of staying in a toxic relationship like that? blind loyalty? its the smart thing to cut him off and its honestly so refreshing seeing a protagonist not be completely naive and realise this.
I sincerly hope you dont have friends like jayce and feel some obligation to stay with them because thats a harmful mindset.

Lol for this your cutting ties with your bestfriend eh it just shows that you guys weren't really good friends like??!! I would never do this to my bestfriend for a guy I met sometime ago just because were I call bs
