25-year-old female, 28-year-old male: my boyfriend changed our screensaver.

Lately, I've been feeling a bit out of sorts, especially after my boyfriend came over to take care of me while I was sick. He brought me food and kept me company while I worked on my college assignments, which I genuinely appreciated. I even made him some food since he only brought a little for me. However, during our time together, I noticed something strange—he changed his screensaver of us back to his original one. This felt hurtful and made me wonder if he was concealing something or if he simply didn’t want anyone to see it. This observation led to an argument. He insisted that he has every right to change his screensaver whenever he wants and didn't think he needed my permission. He pointed out that the core of our discussion stemmed from my issues and said it was on me to express if I wanted him to keep the picture of us. He also mentioned that conveying this through anger and emotions wasn’t acceptable. I’m concerned I might be coming across as overly negative. Am I reading too deeply into this situation? I acknowledge my part in how I managed my feelings, but I still feel uneasy, particularly since he has a female friend visiting from abroad and they're planning to hang out this Saturday. It’s hard not to wonder if his decision to change the screensaver is connected to that, especially since he hadn’t changed it until now.
