Thank you to everyone who provided feedback to me. I do believe face-to-face would have been a better option. I only see the coach once a week at games so I felt compelled to email instead - it felt time-sensitive. But I think the whole thing was pointless - I know how stubborn this guy is. And as my husband said to me, he's more receptive to men than women. I don't know why I continue to think he's a nice person when all of my serious interactions with him have been so upsetting. All of the chit-chat and social interactions with him are pleasant, but he can't accept constructive feedback that is even cushioned with positive feedback. It is what it is. My husband is part of the coaching staff though, so I don't see us changing teams, and my son loves his teammates. I just have to accept the situation and not let it aggravate me. Thanks again.
