Is it possible she came back only looking for friendship even if she was now more intense and getting closer to me?

She knows I like her cause I asked her out last year and we flirted a lot. But she slowly slipped away, thought she wanted nothing with me and then came back, more intense than last time and getting even closer. I don't know what else I was supposed to think of that so I started to flirt with her too. We made plans, her idea, to meet up one weekend, but she cancelled again and her intensity dropped again. She answer if I text her but doesn't seem likely she wants to reschedule, more so with a lot happening in her life. I don't know if I screwed up somehow
