When I was a little boy I met my cousin for the first time. The first few things I noticed about him, is that he had a huge and brittle ego,  he is a pathological liar, and he never reflects on his own actions. He also has the tendency see me a black sheep, and he keeps seeing himself as my savior ( or herder) which is absolute BS and very narcissistic view on reality. Now you might thinking "yeah he was still a kid people grow up." Yeah it got worse through the years...
 
Now I usually avoid hanging with my cousin, but like once or twice a year I meet up with him to see if everyone is still breathing in my fubar family. I live in a small apartment complex, with two other couple. we have two front door, one to the complex, and the other to our own front door. I trust my neighbor s a lot, I've played online games for three years with these guys and we still play till date, and if anything happens to my pc, that also means they lose a player, which would mean they would have to play with random players which has given them a couple of mini breakdowns through the years. So thereby saying I also have my deterrence. So we get along just fine, that's also correlated to the reason why we often don't close our own front door in the morning and afternoon when we are at home, we also usually knock and wait, and if they ain't home, then fuck it. One day my cousin shows up at my front door of my apartment complex (he stated that someone opened the door for him, but no one except us was home at that moment.)  i'm at home with my gf and we just took a shower and we're suiting up for work, so we're almost butt naked. when all of a sudden I hear a faint knocking on my front door, I look up and tell my girlfriend if she heard something? All of a sudden my cousin walk in unannounced and just waves hi to me and my gf. I'm in shock at this point, and feel kind of messed up, because this is something I don't deal well with, my mother didn't know what the word privacy was, and had a very large tendency to just barge in unannounced without saying a word. So I felt a bit triggered and started yelling at him that I didn't appreciate him just barging into my house. I did not use any profanity. His reaction was to twist the situation around and scold me for scolding him on this matter. Eventually I was appalled and I took his rambling with disdain , my cousin had the audacity to tell me to 'don't blow a fuse' when he barges into my house, like Kramer from Seinfeld, and then scold me for not inviting him in, while i'm in my underwear, and my gf is hiding in the bedroom. After I told him to leave, he still won't talk to me till this date, (not that I actually care, but I guess it's a thing now) but now my  family thinks i'm an asshole because I wasn't hospitable enough for him. AITA for not wanting my cousin randomly in my house?
