Pay attention to differences in your communication styles and make adjustments as necessary.
Matt and I communicate entirely differently. When we cook dinner together, for example, I usually gush about my day. I let him know about everything that frustrated me, made me elated, surprised me, or induced laughter.
Matt, on the other hand, is a listener. As a listener, he spends more time asking questions of others than actually talking about himself. Before I really gave it much thought, I assumed that Matt just didn't want to share all the ups and downs of his day. I assumed that he approached conversations the same way that I did: If he had something to say, he would say it. If he didn't have anything to say, then he wouldn't.
It's a dangerous combination because I could easily dominate all of our conversations with my own voice. I've had to realize that Matt actually does have a ton to talk about, but he needs others to treat him the same way he treats them: by asking questions.
So now I intentionally ask questions to get Matt to open up and share everything that he wants to share. I know it seems like common sense, but it took us awhile to realize and articulate our communication differences. He assumes that people don't want to hear what he has to say unless they ask about it. I've had to explicitly point out that I do want to hear what he has to say, but I don't always think to ask about it because I just assume that he will approach situations the same way I do. Each of us has modified our communication styles to equalize our sharing relationship: I ask him more questions; he makes an effort to share stuff without being prompted. It's definitely a work in progress (and an important one!).
What about you and your partner? Do you have different communication styles? How do you navigate those differences?
