My boyfriend left without saying anything ~ Well, let me enjoy being alone ~

I turned the doorknob, but it was locked. "Huh? Did he go out? Makoto?" When I came home from work, all of my boyfriend Makoto's belongings, whom I was living with, were gone. I hurriedly called him, and Makoto said he wanted to break up because he lacked confidence. What do you mean by lacking confidence? Why did he suddenly leave? Would he not have left if I had expressed myself properly in words? Why? What for? Whatever. I'm going to enjoy being single! *Thank you for reporting typos. It helps a lot! Since I'm writing with momentum, the settings are loose. I'm starting to notice that there aren't many scenes of being single...
