Things happen for a reason and maybe she wasn't meant for you. If you are destined to meet up, it will happen.
This shit sounds cheesy but I really believe in that stuff. Happened to me. I met my husband at work, though he was just my boss at the time, so we didn't get together or anything, but he expressed interest. I was leaving a year later for college and he made sure I didn't leave that day with him driving me to go out to eat. I didn't see him while I was in school, though we spoke sometimes online, and then I just happened to email the HR lady and told her I was done school for the time being and if there were any positions opened there. I wasn't thinking of getting with him, just wanted my job back when I was available to work again. There was an opening, I got back in, he didn't let me bugger off ever again, lol.
I could have easily gotten another job but something just told me 'try *insert job name*' and there just happened to be an opening.
