Do I still have a chance?

Lately I've been noticing this gorgeous girl at my gym. I didn't talk to her because her face looked very serious but I also noticed she would smile to me every time I walked past her.

Today I grabbed a bench and went alone to a corner in the gym. She then despite having lots of space to choose came to workout next to me. I was doing very heavy one legged hip thrust sets and in one of the sets my bench flipped over and she came to help me. Then we stuck conversation for an hour. She asked lots of questions and was constantly very close to me she even touched me a few times. Eyes constantly locking and in my opinion we have chemistry. She then proceeds to tell me that she is moving to the next town very soon so she is going to change to another gym. When I was about to ask her number she left in a hurry but before leaving she turned around and said she will try to come one last time next week before leaving.

I am frustrated that I didn't manage to get her number today, wondering what I could have done better. Do you guys think she likes me and I will get my chance next week?
