Why does an ex want my attention?

She broke up with me and said she needed space. After the break, she kept texting me. Ended up stopping. Then, she would always try to be friendly with me. After, she was being cold and bitchy. Most of the time, she would have her back facing me and didn't want to acknowledge my presence which was fine.

All of a sudden, she's becoming extremely friendly and teasing me all the time. Now, she's even play fighting me and mocking me. She's clearly trying to get my attention.
