Are these girls just immature?

I’ve had this a couple times now I would make eye contact with a girl. and she would just go and talk to another guy trying to make me feel jealous. and not that they weren’t attracted to me I just don’t understand. why do this I was going to approach her but this just ruined it for me honestly.

It's hard to know without being there. She's either not interested or playing games. Either way, it's best to move on.
