His bother finally shows up and dude just leaves me and his other friend hanging and goes with his brother. Well me and the other dude don't know each other but we did bond over some beers, and we just started talking shit about our other friend , about how many other times hes done us dirty and shit. we go back to his place have some more beers until we decide to call it a night and who do we see trying to get inside his apartment but my friend. He was taking a piss next to his apartment because couldn't open his door, so finally he spots us, we try to get his door open for that motherfucker but he bent his key trying to open his door. We tell him we can't open it to get the land lady to open it, well hes drunk/high not really to sure, so hes fucking confused. the dude who he left with me, we are now cool, starts telling him off about why he just leaves us like that. our friend ignores him and continues his shit and asking me to go with him, I was like Iike sorry bro going back to my place and we left dude stranded outside his place.
So what you guys think should I have just told dude fuck it I'll help you out or was it alright for me to leave

tbh I think I made the right decision dude has fucked up to many times for either of us to really trust him any longer
