Did the little security guard go to the university to ask his girlfriend out only to see her break up with a male classmate?

In the first half of the month, I haven't seen her for many days. I missed her, so I called her. I originally wanted to say hello to her, but she answered the phone in a perfunctory way and was impatient with me. She said that she was studying for herself last night and reviewing her lessons, so she told me not to call her casually in the future. I am dumbfounded. This is the rhythm of her breaking up. I feel very uneasy and sad. I wonder if I did something wrong? After this call, I couldn't sleep for several days.

Last Monday morning, it was my turn to rest again. I went to see her at school. Before I got to school, I saw her and a boy of similar age coming out of a convenient hotel at the school gate. They were very affectionate arm in arm. It seemed that they had just checked out and were going back to school. At that time, I was shocked. They didn't notice me. Before I knew it, they had already passed by. I pretended to be calm and asked her to have lunch as planned. She came on time, but when she was eating, she frequently looked at her mobile phone and chatted with others on WeChat, and she was still absent-minded about my clothes. I asked her if she was okay, and she said nothing. After eating in a hurry, she put down her chopsticks and said hello and left. I had to leave disappointed after sitting on the account for a long time.

In the evening, I couldn't help but call her to ask about her coming out of the hotel. She said that several high school students came to Wuhan to look for jobs and entrusted her to book a room in the hotel. It is reasonable to listen to her explanation, but why did she book a room with a boy? Besides, it is cheap and convenient to book a room online now. Do you still need her to go in person? Is she lying to me? To tell the truth, I always feel that I haven't been to college, I'm a security guard, and I make less money. She's a college student, and she's beautiful. I really feel a little inferior in the face of her. Therefore, I dare not question her, for fear that she will be angry and I will simply say goodbye, but I'm not willing to make myself a spare tire in a muddle. Should I continue to chase it? What should I do now?
