What is the experience of being single for four years?

When freshman year, still like high school classmate, but only found out in a chat, she had already talked with her boyfriend 6 years, then I hurried to the end of the conversation, and then no longer contact.
Second year, thanks to lol, I was basically addicted to games, so there was no idea of finding a girlfriend.
Third Year, thanks to the Oracle and watchman, successfully quit lol, fell into another pit.
Senior four, thank world of warcraft and King Glory, also dropped the pit.
Sometimes I have fantasized about finding a girlfriend, but for some character reasons, I met too few girls and didn't talk about it.
After all, for me at that time, the game was very important.
Being single is nothing. Many of my college classmates are single, but it doesn't affect our life.
All in all, it's all about getting me into a situation
