If a girl acts like this around you..

Maybe she is just acting chill around you just incase you don't like her back , I think you should just tell her how you feel

it could be that she likes you,...or it cud be that she's just the friendly type. if she likes you then she's having a hard time figuring out how to get ur attention yet let you know she likes you without losing her cool. if she doesn't I'm sure she thinks you're a nice guy. but you like her...so what to do? well try to make her know that you like her. don't tell her or don't make anyone tell her.send her a sign. if she likesss you she'll react to it. if she doesn't she might not even notice the sign.

goodluck

Something was on her mind long enough over break to change how she wants you to see her. Maybe she was waiting for you to move, maybe she simply decided to move on. It's hard to tell. Ask her out and see what she says, something casual and not threatening in a way that she may feel pressured. Or take the short road and talk to her about what you are feeling.

i think she has lost interest (got bored) or has found somebody more interesting. But talk to her to confirm it. That's the only way.

You need to learn Game

1. tease and make fun of her
2. reply to her direct questions with bullsh*t answers
3. act cocky, in a funny way
4. "Agree & Amplify" - this is from Improv. Never say "no" to a question or accusation. Agree with her and "double-down".
