I read your first paragraph in my voice. I need to have the same exact conversation and it is SO awkward.

It is definitely important that you bring it up with him, though. You are allowed to have feelings and you do not need to feel guilty about them. Even if what you're communicating is not what someone else wants to hear. Holding that kind of stuff in tends to be a recipe for resentment.

Telling your husband how you feel gives him the opportunity to choose whether he wants to change or not. If not, maybe the two of you can figure out workable steps to improve together. My best suggestions are to 1.) make sure he doesn't hear you blaming him (maybe use "I" statements or something similar) and 2.) be supportive but reinforce that you envision marriage as a growing relationship that encourages the growth of each partner. I wish you much luck!
