I (21 M) feel terrible every time I discuss my emotions with my girlfriend (21 F).

I've been dating my girlfriend (21F) for the past two months, and I’m feeling really exhausted. From the start, we both agreed to be open and honest about our feelings. Initially, we faced some typical relationship challenges, but we worked through them together. I put in a lot of effort to make her happy. However, just one month in, she started getting upset over what I consider minor issues, shutting down communication, and disappearing. Here are a few examples: * I told her multiple times that I was tired and planned to go to bed early, but it still upset her. * While we were watching a movie, I went to grab some water and she sent me an Instagram video that I didn’t check out because I wanted to focus on the movie. * I spent time chatting with my friends. Last week, I finally shared my feelings about her behavior, explaining how her reactions made me feel awful, but I also reassured her that I was open to discussing things. Unsurprisingly, she didn’t take it well. Yet, the next morning, we talked as if nothing significant had happened. Today, she sent me a video saying, *"When I try to express my feelings and he responds with 'I hear you, baby,' instead of 'Why do you have to make a problem out of everything?'"* She added, *"Unfortunately, you made me feel like the second part."* It appears that I’m somehow at fault for not fully understanding her feelings. Sometimes she claims it’s merely *"her attitude,"* which I don't think is a valid excuse. Every time I try to express my feelings, I end up feeling like I'm doing something wrong or saying hurtful things to her. This situation is becoming overwhelming, and I don’t feel at peace in our relationship. I find myself overthinking every little action, which I really dislike, but I still love her. I’m not sure if this is just because it’s my first relationship, but I worry that if I choose to end things, I might come across as someone cruel who hurt someone just trying to be understood.
