I am having problems in a relationship. I recently moved in with my partner, and our relationship was going well. We got into a fight, and then all of a sudden, it felt like it was over. I am confused. How does someone go from hot to cold so quickly? I feel angry and scared. I feel abandoned. And I can’t find a way to talk about my feelings with him. He is so defensive and just keeps explaining and rationalizing. He isn’t able to hear me. What is going on? What should I do?
