My coworker has been acting weird. Is she just being friendly or is there more to it?

One day while i was eating lunch she decided to join me and started asking me why i get nervous and quiet around girls. I said “i dont know” (i have a crush on her). She then started asking me if i never talked to girls and if i dont have a girlfriend. I said no.

The next day we were standing outside the office and while we were talking she got really close to me (within personal space) and then places her hand on my tummy. I was uncomfortable and moved back and she did it again and kept it there. Someone came and she moved back.

the next following days she started to join me for lunch. Everyone else goes out to eat but i stay in the kitchen to eat. And now she stays there with me while all others are out for eating. She will say hi and ask me how i am. Then she asked me my hobbies, where i studied from, future plans and so on. Small talk basically.

The touching seemed a bit more than being friendly but the rest seems fine. But i do think asking someone if they have a boyfriend/girlfriend is not appropriate at work. Moreover she is the HR so she should know better.

now I’m not sure what she wants and why she is doing that.
