Is she playing me?

Hi all,
Long story short, i started talking to a girl about 2/3 years ago, we were getting to know each other. However, my ex started stalking her and we stopped talking.

She got into a relationship which didn't work out, and i started dating around. However, could never settle as she was always on the back of my mind. We got back in contact with each other after her break up, and i helped her through it all, we got extremely close and would talk to each other about almost everything.
A couple months ago i got the courage to tell her i had feelings for her but i will not pursue her unless she makes it clear she wants me too. She replied she doesn't know how she feels, but knows we are in each other lives for a reason. After that she started acting really weird, and taking forever to return back my calls and texts, so i fell all the way back and stopped talking to her.

To my surprise almost a month later (with no contact), she messages me asking why i haven't contacted her and asked me to come and see her. I said okay but had a very busy schedule so i said in 3 weeks. No problem we started talking every day once again. But every time i mentioned the details regarding meeting she would take ages to reply or didn't at all.
A few days before we were meant to meet she said she was ill, which i knew was true as her health had not been the best of late. She asked to reschedule, however, once again now i try and get details once again she takes ages to reply (which can be between hours - days or not at all). I need these details as she lives 3 hours away and i need to book my train ticket.

Am i wasting my time?
