She [22 F] wants some time apart but isn't looking to end the relationship. I'm [25 M] feeling scared and unsure.

Hello everyone, I'm seeking some advice and would like to share my situation first. My girlfriend and I have been together for nearly a year. She is currently studying abroad in Sweden while I’m based in the Netherlands. We had planned a trip from March 4 to March 9, 2025, for me to visit her (which I did). As her first partner, we experienced a very physical, affectionate bond when she was living nearby. During a night out, we had our first argument when I was walking home after a few drinks. I crossed a line and said some things without considering their impact. I often struggle to manage my emotions. After our argument, we spoke two days later and decided it would be better to talk in person, so I traveled to see her on March 4. When I arrived, she was waiting for me at the train station. We hugged, and it felt great—a sense of trust reemerged. We walked to the hotel where I checked in, and she joined me in the room while I got ready. We went to a restaurant, ordered some drinks, and I expressed my sincere apologies for my behavior, telling her that I would start seeing a therapist to work on my issues. She seemed relieved that I was committed to self-improvement. After that conversation, we headed back to our separate spaces, agreeing to meet at 10 the following morning. We had some deep and sometimes uncomfortable discussions. When we visited her apartment, I asked her about our future. She mentioned needing time alone to focus on herself, as her homesickness and feelings about our relationship felt overwhelming. I interpreted this in a very black-and-white way, asking if she wanted to break up, which wasn’t her intention. She clarified that she needed time to heal from our argument and felt a bit suffocated by our constant communication. She encouraged me to work on being less demanding, and I agreed. She also expressed a desire to build her self-esteem. We both recognized that we had been suppressing our feelings and longed for physical reassurance. So, we embraced, kissed, and spent the evening watching a series together. She mentioned wanting something more than just kisses and hugs, but I felt it would be better to maintain some distance to avoid further pain. On Thursday, we both flew back to the Netherlands. In the morning, we spent time in my hotel room (we decided it was best to sleep separately). We had more hugs and kisses, and she even expressed her love for me; I was more cautious in saying it back. At the airport, we reassured ourselves that this was what was best for us. She said that if we each focus on our personal growth, we might have a chance to reunite. We shared intimate moments at the airport and on the plane, but eventually, it was time to say goodbye. She ran up to me, hugged me tightly, and whispered, "We’ve got this. I love you, and I’m so proud of you." Then she turned and left. After our time together, I realized I had left some makeup at her place and dropped it in her mailbox the next day. She replied, breaking our no-contact agreement, saying "Thank you ❤️ I love you ❤️." That was our last contact, and we agreed to talk around April 29. Right now, I'm really struggling with my emotions. Although her words and the positive physical interactions give me hope, my mind keeps racing with worries—what if she decides being alone is better? It’s upsetting to think about, especially since she mentioned that if I felt the silence wasn’t beneficial and wanted to end things, I should let her know. I fear she might be the one to make that choice. I'm anxious about losing her; I truly believe she is the right person for me. I know I'm likely overthinking everything, but I can't help but feel scared, confused, and uncertain.
