There's this girl who goes to my Gym and she asks me to hang out quite a lot.?

I haven't really said that much to her, we've only talked briefly. I know some of her friends and they have a good time with her. I am not sure how she feels about me. Our gym has a games club as well. I've played games with her once a week, for the last two or three weeks. The other thing is today, I was playing badminton with her and some of our friends and I had a game with her, before the end of the session. We both had to go at the same time.

She asked me If I wanted to walk to the bus station with her, because I told her I was getting the bus home and we both get the bus at the same.

Then she said she had to go and she went on her own. I left straight after her, because I wanted to catch up with her.

I walked passed her at the Bus Station and she said, so you did leave at the same time as well, that's a shame I would've waited and gone with you.

I said yeah, i thought we was going to walk together and she then she laughed. I'm not sure if she's flirting or just being friendly

I am trying to work out if she has any feelings towards me and If she likes me.
