I am divorced mother , the father kicked him out and hes been in and out of jail since 18.He's a compulsive lier, He is suppose to be on medication but is not, he smokes weed gets drunk and pulled a knife out on his brother at his own house, then again today at my house as if trying to stab him. He dont listen to me, His father dont want him, nobody wants him and I dont feel right kickign him out, because he is unable to find a job due to warrants he has and he cant pass a drug test and hes not very smart at all, I dont want him ending up dead if I kick him out. he is a wanna be gang banger kind of guy and listens to rap music even singing it, he stays home all day and night and makes me clean and cook when i get off work I dont know what to do any help or advice is greatly appreciated. He his his girlfriend and they fight all the time., Hes really helpless like a teenager mentality I dont know what to do. He really gives me a big time guilt trip when I try to tell him anything.
