<human>: We dated for a year, it was fun and we got along well. After much distress on my end due to his apathetic nature, we broke up and decided to be friends instead. We still have sex, we go out together, we still hang out with other friends, we spend the night together once in a while. We're basically friends with benefits - both him and I wanted this set up. 

I am 100% confident I have no intentions of getting back together with him. He's been talking to one of his other exes, which would have been a deal breaker while we were dating, but now I don't care about it.

But lately I realized what a shitty friend he is - like borderline douchebaggy even. I hold him up to the same expectations as I do other close friends, and damn is he falling short on a lot of things. I still care for him after everything that has happened, it's in my nature. So naturally I want to see him succeed in future relationships. Would it be in his best intentions if I call him out on being a shitty friend? And that he needs to work on being a good friend? He was the one who was insistent on being friends after the breakup, so I don't know why he's treating me like crap. Really, I could walk away from all of this.. but alas, my good nature wants to help him out.

He also hates talking about these things. How can I bring it up?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Dated. Broke up. Now friends. He's being a shitty friend. I want to see him succeed in future relationships. How can I help him?
