I will admit that it is very pathetic how long I have known this person, while trying to get rid of him. I meet him 4 years ago in high school when I didn't have many friends and neither did he. I was younger and dumber at the time, and I didn't know good friends from bad friends so I started hanging out with him. I realized I HATED him almost right away, and I've been trying to get rid of him ever since. He is VERY clingy and came on really strong really fast. He is a terrible friend. He is rude, irresponsible, untrustworthy, disrespectful of my property, and he is very uncomfortable to be around. Even after 4 years I don't feel comfortable being around him. I can't just avoid him, he will call me 10 times a day and leave messages. Eventually he will show up at my house unannounced looking for me. I have told him outright 3 times that I don't want to be friends with him anymore, but somehow that didn't work. Seriously, nobody wants to be friends with him because he is loud, obnoxious, rude, and very disrespectful. Above all though, he is an idiot. He is an outright moron who just DOESN'T GET IT when someone is dropping hints that he isn't welcome. I have basically separated him from everyone else in my life and I'm just trying to get him to leave. Right now he is trying to start some big illegal scam and he won't start it until I get involved with him. I don't want to do this because firstly I think it's wrong, but more because I KNOW that will get caught because he's an idiot. When I tell him that I'm not doing this illegal bullshit with him, he gets angry as hell and starts calling me a fucking pussy or a fucking nigger. I guess he just doesn't understand that I don't want to go to prison. I haven't called him in like 5 months, he is always the one calling me. After 4 years of knowing him, I can't help but feel bad for him because he thinks we have a valuable friendship (to him maybe) but I definitely don't think so. He would do anything for me to keep me around, which is why I'm having a hard time just completely cutting off communication with him. What should I do?
