So I meet this girl who works by me on her cigarette break. We talked for a minute but she had to go back. While he left I grabbed her hand and jokingly said "you broke my heart" I wanted to get her number so I came back the next day, she wasnt there, next week she wasnt there. I mist have went back 7 times. And I could never find her there. I know now I should have asked for her number the first time I saw her. But I wasnt quick. So should I keep going back until I find her or move on?
