My boyfriend raised his voice at me, and I’m unsure how to process it. I could use some advice.

Today wasn't the best day for my boyfriend. Something triggered his anxiety about a physical issue he often worries about. Due to past trauma, he tends to be avoidant and self-conscious about his appearance. Earlier, someone made a comment that unsettled him, and while he shared it with me, he quickly shut down the conversation when I tried to reassure him, indicating that he didn’t want to discuss it further. I gathered that he was feeling unwell because of it. As the evening went on, we spent time together, though he was somewhat withdrawn and didn’t feel like talking or engaging in much. Towards the end of the night, I approached him to check in as I noticed he seemed to be pulling away. When I asked what was on his mind, he replied that he didn’t know, and when I speculated it might be about his hair, he said, “think so.” That response left me confused; it felt uncertain, and I often struggle with nuances of communication, like sarcasm. Wanting clarification, I asked, “What do you mean? Is there something else?” He replied with “yeah,” but my anxiety grew, leading me to feel a mental fog settle in, sensing that there was more beneath the surface. Earlier in the night, we'd exchanged kisses and hugs, even though he seemed reserved. However, towards the end, when I suggested cuddling, he responded with “I don’t know,” which triggered my anxiety—I’m naturally a nervous person. I tried to express my confusion over his earlier response since “think so” implied uncertainty. This led to him getting upset, telling me he was “pissed off” and that he had been trying to be patient with me. When I tried to explain my feelings, he raised his voice in exasperation, prompting me to apologize for my confusion, even though I wanted him to know that I wasn’t trying to make it about myself. He said, “I think so,” in agreement with my question, and added that it wasn’t his fault I didn’t understand the meaning behind his words. He felt like I was making the situation about me, and he was unhappy that I had provoked him to yell. Despite his frustration, he offered some comfort, saying, “Apology accepted, but I’m done for tonight,” and that he would see me the next day. Now, I’m left feeling confused. I know that dealing with an anxious person while managing your own mood can be challenging, and I empathize with his feelings of frustration. He seems aware of how his yelling affects the situation, but he tends to be very matter-of-fact and blunt. When upset, he tends to withdraw to avoid further conflict, while I prefer to sort things out since I’m emotionally sensitive and understanding. I’m seeking advice on how to navigate this situation. Please be gentle. TL;DR: My boyfriend got upset when I became anxious because he shut down emotionally, yelled at me, and now I'm feeling confused.
