Being a friend is not about that much maintenance. You can still be friends with someone who has these flaws in your life. So it goes both ways. You shouldn't let flaws define a friendship, and you shouldn't let a friendship define your life either. All of the people you mentioned I would still be friends with. The only thing I would "maintain" with them is keeping in touch or hanging out and maybe being there for them if they have a genuine problem I can help with.. but the help of course has limits... If I can't help them, it doesn't mean I'm not their friend.
