My boyfriend (21m) mentioned to my best friend (18f) that he thinks I’m being too distant. I’m a 19-year-old female, and I’m not sure how to address this. What can I do to improve the situation?

I’m a 19-year-old female, and about a week ago, I had a really traumatic experience. Since then, I've noticed that I’ve been acting differently—more reserved and less outgoing—as I try to come to terms with what happened. This situation is even harder because it coincided with some personal struggles I was already facing. I kept my boyfriend, who is 21, informed while everything was happening, and he was aware of the issues I was dealing with. Whenever we met, I apologized for my quieter demeanor and reassured him that I truly enjoy our time together. He always reassured me that it was alright. However, I found out two days ago that he had messaged my best friend, expressing concerns about my distance and suggesting that he thinks I might be losing interest in him. This really upset me for several reasons: A) He reached out to my friend instead of checking in on me, B) He knows I’m going through a lot and I’ve made it clear that my feelings for him haven't changed, and C) While he claims I don’t text or call him as much, he’s never made the initiative to contact me first. On top of the traumatic event, I'm also a college student preparing for finals, and with the holidays approaching, there’s a lot on my plate. After learning about his message to my friend—who he asked not to tell me—I reached out to him again, expressing my apologies once more for being quieter and explaining the reasons: the trauma, school, and holiday stress. He said it was fine, but today in class, after I hadn’t replied for about 10-15 minutes, he started spamming me about wanting to change his schedule at work to spend more time together. It’s just frustrating because he claims I don’t initiate communication, yet I’m the one who reaches out first every day. I talk about wanting to see him and making plans, and despite my apologies and explanations, it feels like it’s never enough. What hurts even more is that instead of checking on me, he chose to confide in my best friend. I’m at a loss on how to address this situation. I really like him, but this constant feeling of being suffocated is overwhelming, and it seems like no amount of communication can resolve the issue of him feeling I’m too distant. In short, I feel like I’m not getting this right. My boyfriend thinks I’m too distant, and I’m not sure how to fix it. Any advice?
