Help me understand the body language? Does she think I’m creep?

The girl that I like in my gym since the last two months, sometimes comes with a guy (this is the only second time I watched him). They don’t behave like couple. Today I’m doing stairs machine. So this guy and she looked at me once, for the first time she walked near me, started doing stairs in the next next next machine. I’ve never seen her doing stairs in the last two months. So This guy looked at me few times and went so far away from my sight. And Once I did my stairs machine after 25 min, I came to drink some water at the fountain which is right behind the stairs machines. As I want to watch her signs. I simply drank some water and turned back, she is done with her stairs machine and sat on the lowest stair with her head down tying her shoe lace or doing something. I didn’t notice or give much look at what she is doing. I breathed and drank another sip of water and walked away from the spot to the other corner of the gym. Few minutes later, this guy and her walked out of the gym together.

what are this signs mean, should I give up on her? Please help.

If she is not into me, why would she wants to come to the stairs and finish right after I finish and sit there.

Everyone says approach someone when they’re not working out. So I don’t know if she is baiting or genuinely done or giving me a hint to approach her.
