Differences in personality types can have a lot of effect on marriages. I respond to the outer world emotionally first. My husband responds with logic. I am an extrovert, so I tend to react openly immediately. My husband is an introvert and he only responds after much thought. When I would get either excited or upset about something and babble over about it, he would sit back, cross his arms and put on his “here come the judge” face. After several moments of waiting, I ‘d get frustrated, either disappointed that he didn’t share my enthusiasm or angry because he was looking judgmental. And unfortunately his first logical problem solving response is to focus on the practical problems or negative aspects. After some years of marriage, without realizing it, I began to try to push his buttons just to get him to express a feeling of any kind. The problem with this is the introverted thinker may go years without responding openly to provocation, only to one day reach overload and either explode violently or simply leave and not look back. Fortunately, since we had five young children, I recognized my pattern before my husband reached overload. I have since realized that when asking him for a yes or no decision, I need to give him plenty of unpressured time or he will play it safe and just say “No.” The same with arguments. I now state my case and go wash dishes or do something else while he works out his response, and then gets back to me. Unnatural as this is for me, doing this brings much better results and lessens conflict. I’m pretty sure that it is a total shock to one of the spouses, when marriages disintegrate from unrecognized inborn differences such as these.
