Chalk up some of the communication disagreements to a difference in men and women. Decades ago I stopped reacting to what I saw as eye rolls and sighs, having previously wanting to "talk it out". My hubbie was and is still near perfect, but these little signs of irritation were just that, little, inconsequential and not requiring hashing out. Now I just move on, and in no time, things are back on track. Now about the snacking.... I guess I would just ask him to go back to the kitchen and get me the same as he has (if that's what I wanted).
I guess I see these issues as not so much being about intent, but rather personalities. And, in a marriage, some acceptance brings an abundance of good days. Oddly, it took me years to realize how many of my personality quirks were the very reasons for my husband's eye rolls, which he was working on accepting! All my best.
