Am I mistaking kindess for something else?

Another gym story Im sorry.

The gym I go to is chill and most people are really friendly, so much so I talk to a few people every time I see them. And people have been very nice to me, I am also am not from the area but everyone in the city is also friendly.

I realized I was talking to people through this one girl which was rude so I felt I needed to introduce myself. One day I did and it went well then later I had a question and we talked longer, I said okay I’ll let you finish and she see said see you tomorrow. At the very least I felt like I made a new gym friend and that it was no longer going to be awkward.

A week went by and she smiles and waves at me when we walk past so I stop and she states how she sees me all the time here to which I responded.

Then the next week I start working out and we make eye contact and she waves at me which catches me off guard. And then when she leaves also waves goodbye.

Now it’s to the point where if I don’t wave I’m being rude so every time we make eye contact we wave. I’ve spoken to her a few times and every single time she doesn’t break eye contact. She asks questions nothing crazy but there is never a sign of please go away or stop talking to me.

One time I just didn’t have a follow up for a second and she was just staring at me almost like waiting for what I had to say. She even took both AirPods off when we were talking.

One time she didn’t see me but saw me last second, stopped walking and waved before going to another area.

I talked to her today about something I mentioned previously and she was all smiles when we were talking briefly.

In my head she might think I’m just talking to her like a normal gym friend. I’ve never complimented her.

But in my head there’s no way I would wave at someone every time I saw someone if I was in a relationship or didn’t like someone.

I do know I need to eventually ask but i genuinely can’t tell if she is just cool / nice / kind or more than that.
