This is the first time I've liked someone. I've done a lot of stupid things. There's a problem with my relationship. I'm very confused now. Everyone, help me!

Thank you for reading these words patiently I met a girl I liked very much. I fell in love with her at first sight. After dating her for a while, I realized that I really liked her, so I tried to make friends with her. Because it was the first time I liked someone, I did a lot of stupid things with her: The first time she asked me out, I was 9 minutes late. The second time I asked her out for Christmas, I was 6 minutes late. The third time I asked her out for New Year's Day, I was 1 minute late. I made her very angry. Then I explained (although it was all true). But she told me later that the more I explained, the angrier she got. I realized that sometimes you can't explain. The first time I gave her a present for Christmas wasn't very nice. To put it bluntly, it was a little stupid, but at that time, I really had no choice. I was too busy to take the CET-4 exam on the 24th. Moreover, because the note was written in a hurry, it had no literary talent. What was worse was that there were many typos! She Doesn't Like Me Treating Her to Food (Because she had never eaten with a boy before, she was not used to it.) Now it was winter, and it was very cold outside. She could only go to places like cafes. So every time she went there, she would sit there and chat until her mouth was dry. I wanted to buy her a drink, but she always said no.(Because she had fallen and hurt once, I went against her wishes and took her to the hospital, which made her very angry, so I didn't dare to do anything she didn't want to do anymore.) In my description of myself, I exaggerated some of my words when I described myself as being careful. I thought she would like more careful people, but later she said that she preferred male chauvinistic boys and said that she had formed these opinions when she was dating me. After I met her for half a month, I got to know her roommates. Because I had never been in a relationship before, I heard others say that they wanted to pursue a girl. The people around her were very important, so I invited them to many meals and told them that I liked that girl. I asked them to help me and provide me with more insider information. On January 2nd this year, they somehow told her that I wanted to pursue her. Then, she sent me a text message to tell me that she used to like me, but I didn't know when this feeling was erased during the dating process. Then, I didn't talk to her for three days. I used this time to write to her, but just as I was about to finish writing, she sent me a text message saying that if I didn't answer her call, she would never talk to me again. I had no choice but to agree to meet her. This time, I made a very big mistake. It was this mistake that caused her to no longer trust me: When I met her this time, I told her that I was a national defense student.[I was a reserve officer recruited by university students in the army. I was usually the same as an ordinary university student. There was no difference. After graduation, I had to serve in the army for five years. I would be an officer with the rank of first lieutenant. I joined because I could avoid tuition fees. In addition, I could earn enough living expenses by tutoring myself. I could be completely independent (My family's financial situation was good, but my parents were too strict with me.) I wanted to get out of their control by standing on my own feet. At that time, I felt that she thought that I had lied to her. Anyway, she looked very wrong. The next day, I gave her the letter. It contained all my words. I wrote in the letter that I liked her and I loved her (it was only two and a half months since I met her). I hoped that she would give me a chance. Then she sent me a letter, saying that she would give me a chance, but she could not accept me now Later, I regretted it. At that time, I told her about all the bad things, but I had to mention this matter to make her think that I was lying to her. From then on, she didn't pay much attention to me. She either refused to see me or kept far away from me when she saw me. After that, it was the final exam and the holidays. I didn't see her at all. Her sister came to her dormitory when the holidays were approaching. She told me that I was not allowed to send her text messages, call her, or see her. I agreed, but I was revising those days. Without her, she couldn't study at all, so I called her at 11:35 at night. I didn't expect that her cell phone was still on (I thought her cell phone would be off, so I would give up after calling). I asked her,"Is your sister here?" and hung up. After a while, she sent me a text message and scolded me for two hours, saying that I didn't keep my promise. She said that I was always late. She said that I couldn't even keep our small agreement. She said that I didn't understand her at all and never thought of understanding her. Then she never talked to me again. When the holidays were coming, her sister came to her dormitory. She told me that I was not allowed to send her text messages, call her, or see her for a few days. I agreed, but I was revising those days. Without her, I couldn't go in. I called her at 11:35 in the evening. I didn't expect her phone to be turned off at that time (I thought her phone would be turned off, so I would give up after a call). I asked her,"Is your sister here?" Then I hung up. After a while, she sent me a text message and scolded me for two hours. She said that I didn't keep my promise. She said that I was always late. She said that I couldn't even keep a small agreement between us. She said that I didn't understand her at all and never thought of understanding her. Then she ignored me again. Valentine's Day is the day after tomorrow, what should I do?
