What experiences have made you feel "I deserve to be single"?

I really can't feel this, but it was reminded by others that I realized why I was single for so long!

Because I didn't know them well at first in the first year of college, I decided to have dinner together to get familiar with my classmates' feelings, because I didn't know anyone well. When several boys were looking for a place to eat and contacted the girls by mobile phone, the girls came one after another, leaving only one girl, because when the girl first came, she chatted with me very enthusiastically, so the boys in our class asked me to pick her up. People in their dormitory said to pick her up, so I went reluctantly. When I got downstairs in the girls' dormitory, I began to call others. After a while, she came down and was about to take her away. She said she was sorry to wait for me for a while. I was stupid enough to believe it! I just waited and waited there, and then I thought to myself, I went late, and people finished eating? What should I do? I am really hungry. Then I decided to go first, pick her up to sing after dinner, and left by myself. . .

Just knowing the birthday of my secret crush, I gave her a nail clipper, because I thought her nails were too long and it was easy to scratch others, and then it was gone!

I went to play with my friends, met a female classmate in our class on the bus, and then went to a place together. When I came back, a girl bought a lot of things and asked us to help her, because when I took them, they had nothing, so I said, "That's all that's left, take them yourself!" Then this girl didn't let me take anything (? ò ? ó? )

The most important reason may be because of ugliness (? ò ? ó? )
