Should I confront my ex about the way he broke up with me?

My ex of two months ended our relationship about two months ago. He broke up with me over the phone, which I find immature and cowardly (he's 46 and I'm 30). I am over him, but not over the way he broke up with me. I saw him tonight and felt contempt towards him. I will be seeing him weekly because we play on the same soccer team. Should I tell him that he's a coward because of the way he broke up with me? Or should I just not say anything?
