Hey guys , I'm having a dilemma that I would love some unbiased feedback on . It's a bit lengthy , but here is all the details : I am 22 , and I live with a roommate and my girlfriend . I have been out of my parents house for 6 months now and I work full time and go to school full time as well . I am struggling to get by , but I make it . My roommate is a long time friend of mine that I met when we were in middle school . In high school , he mixed in with the wrong crowds and began heavily abusing drugs and alcohol . I do not use any substances as I choose to be straight edged when it comes to drinking and drugs . He went to jail a few times for drugs and because of his probation , he cannot live at his parents house because they own weapons . He was living on his own until 6 months ago when I moved in with him . I moved in because I needed space from my family and privacy with my girlfriend . Because of his past , he blames the world and there not being any God for his hardships in life . He is very hateful and despises everyone around him (not me) . My presence has helped him heal his addiction and help his depression significantly , he now has a good person to rely on and look out after him . He feels that nobody cares about him , but I do . He is a great friend of mine and I would never abandon him . He is also incredibly racist . This is where we had a falling out last night . He was going to play Xbox with me and some of my friends , one of which is dating a black girl . I told him that he cannot say anything racist if he wishes to play with me and my friends and he totally snapped on me . He was so disrespectful towards me and my friends and it was very tough to swallow . He is not a good person , but I love him regardless . I know the person he used to be , and I cannot change our great past . This is the first bad encounter we have had since I moved in , but how do I go forward ? My girlfriend and I are considering moving back in with my parents now , as we do not want his toxic mindset to interfere with our wellbeing . I am just scared to leave him alone in that apartment again . I don't want addiction to swallow him or for his depression to make him harm himself . Am I a coward for thinking about leaving ? What is the right thing to do ? I just feel so disrespected and wronged . I really appreciate any and all thoughtful opinions . Thanks guys .
