In trying to resolve an issue, I hurt a friend and friend hurt me. What should I do?

I tried to talk to a friend of mine about a problem I had with him. He hurt me and I unintentionally hurt him. I’m sorry for hurting him but I don’t think I’m wrong and I know I was in the right for addressing the issue. I do not know what to do because he thinks that friendships should be effortless but I think you should have to work through issues to have any sort of relationship.
