Honestly? You two don't really communicate all that well. There's something lacking when you talk with each other -- awkward silences stunt the flow of conversation, and you might not always understand each other's jokes or points of view.
You can grow frustrated with each other, maybe just to a minor degree -- but it might be more significant than that, depending on other factors. At base, what's going on between you is a disconnect in your individual focuses. This person might be focusing on you, but you might have trouble focusing on them -- and in fact, you might be focusing mainly on yourself. You aren't able to hear your partner because you're so focused on your own ideas, your own path in life. Thus, their needs end up flying over your head, unrecognized and unfulfilled. This isn't due to any kind of malice or even selfishness on your part; it's simply a basically benign disconnect that can be corrected if you both want it to be. You have to admit the fact that there's something not quite right between you, that the ways in which you two communicate tend to irritate both of you; and then you have to make the conscious effort to focus on each other, listen to what the other is saying and respond directly to that. The differences between you don't have to be threatening, or an insurmountable obstacle, but it may take some work to get past them.
