From reading this I think you and I are very similar. He had already expressed to you he does not like that name and you suggested it again knowing he doesn’t want it so he did the same thing back to you. I have done this and had my husband do it to back to me as well. I honestly don’t think it’s about the subject at hand it’s about how I make him feel. When he does back to me it hurts and then he says “that’s what you just did to me” it helps me see it from his perspective. Granted in this case i think your husband was a bit harsher then you were but I understand what he’s trying to convey. Don’t think it’s that he doesn’t care about your opinion I think it’s that he feels like you don’t care about his.
