Girls, My crush is in another city, what should I do?

My crush graduated a year earlier than me, but we did internship at same company over the summer. I asked her to hang out but she always said she had plans or she replied many days later. I started the conversation alarmist every time. And I moved to another city but I will go back after a few months. How should I do to make her interested in me right now?
