What is the most likely reason a girl would ignore/avoid a guy for no reason?

[andre-48]

This girl and I know each other, we've had good conversation. She has made small talk with me when we're alone together. She has stood in group conversations with her feet pointing towards me with her dominant foot stepped forward towards me. Why is she kind of acting like she is avoiding me when I've only been nice to her? She talks to ther guys normally but not me 😔

They just don’t care. OR

You pissed them off so bad they hate you to point of containing their Emotion. And that’s some REAL HATE…anytime a woman is controlling her Emotions…. ain’t no guy who return from or back to a Woman who is controlling her emotions when you’re around her.

But she will happily come near me when I'm in a group, but will more likely talk to me when she and I are alone

She is waiting for you to pull out your Man-Up card and ask her out... she's shown interest by speaking through crowd of people. She's going to think she's butt ugly and that's why you have not asked her out !!! i
