I need some advice with this girl *10points*?

Like i found out she liked me the last day of school but i never got to see her after. And we never spoke to each other ever we just have the same friends and sat at the same table. So i hit her up on twitter like a month ago and she was happy and all and you could tell . But we barley had like a real convo and it ends really quick and i assume she was busy with summer college stuff it was at night so i though she knocked out. But i noticed she didn't answer in the morning like most girls would do if the liked you in my experience. But now when i hit her up she doesn't and or she responds two days later. I dm her on twitter but she didn't answer and i know shes been on twitter cause she retweeted somethings. And its been three days
