Quick and simple question. For context I am a 20yo college student.

How do I deal with chicks that reject me/don't want to move forward, especially when I still see them around campus/classes.

My autistic(joke, not really on the spectrum) self has just ignored them/not went out of my way to get there attention(nexted them). But I'm not sure if I come off as bitter.

Just sometimes feels awkward being around them, especially when I get rejected pretty bad.

Tldr How do I hold myself around girls that hard reject me
