Do you think she could be interested?

There’s this girl at my gym I’m crushing on. We’ve talked a few times earlier in the year but the vibe didn’t seem there. Lately things have been different. I’ve caught her looking at me a few times and she’s caught me glancing a few times as well. Now every time I see her she’ll act like she ignores me and walks past me. But there were a separate occasions lately that has me wondering. The first time I was walking out of the back room and I was zoned out and she was walking into the room and we almost bumped into each other. We locked eyes and she gave me a half smile. Later that day I was using the smith machine and she was using a machine next to me. There’s a mirror in front of the smith machine and while I was doing incline press I saw her watching me until she saw me looking at her. Then a few days later I was doing something on the smith machine which is next to the restrooms, she went in, I finished up and went to the front to get my headphones to do cardio. When she came out she noticed I wasn’t there anymore cause she looked around until she spotted me up front and when we locked eyes she quickly looked away. Then the next day I finished my workout and was getting ready to leave. When I turned around to walk to the bench to put my shoes on she happened to be right next to me waking past. It caught me off guard and she looked at me and gave me a half smile again
