I feel like if she does all of those flirtatious things, just let her keep doing them. Some girls like chasing more. It's fun and feels like a challenge. Don't contact her until she contacts you. She might not quite be at the point where she is totally into you. But by being friendly but still letting her chase, she'll get more attached to you.
did you maybe do some bad stuff in your past, any mistakes she couldve find out? bad reputation? maybe she lost her phone or smthing? stay positiv the stuff above is reaaaaaally good, good luck x (dont thhink she's expecting that..)
Don't think too much dude.. maybe she's busy or went out for something else..
it's common lol don't get panic and screw things up..if she likes you then she'll text you or call you back..If she ignores you often now and then...then you can surely tell that the girl is playing hard to get..
