you start off with "a friend, who is decent" then go on to point out all the reasons he is not what you think is a decent person. Explain why this is a person you label as friend? Honestly I am not sure if you feel like you're obligated in some way to be friendly and connected to this person but it doesn't seem like they are a person you would voluntarily hang out with - I may be wrong but you really don't like them. just find friends that are people you share values and interests with and don't endure this any longer, not worth wasting time and energy in a relationship that is clearly not beneficial to you or even enjoyable.
